We have pretty much covered the DC arrangements of all 3 operators of the class.
The one omission on the topic has been HMAS Bataan.
Commissioned before wars end, but too late for any action, she was fitted with MK IV`s as built.

She appears to be unique in stowage fit, as 2 extra racks were fitted, port and starboard, presumably 2 canisters per rack.
These were present for only a short time, the blue circle identifies them, the red arrows show the rack and loaded MK IV thrower.

Maybe of interest, and not mentioned previous, the 6 canister Mk IV rack was positioned close to the thrower, the upper/outer canister was pushed straight into the thrower cradle, the racking mechanism them moved the next canister into the outer load tray for next reload, a bit like a carousel.
Cheers.

Here's a pic of HMCS MICMAC's Props in 1961. So far the only Tribal Prop image I can find.

Thanks Darren, a rare find.
I also managed to find this shot of Arunta, props are hard to make out, but I can just distinguish the blade pitch.
They appear to match the pitch in your photo also, but I feel there may be an anomaly here.

Both shots do NOT appear to match the blade pitch of the Haida display as presented, what do you think?

I think the Haida display is random. It was moved when the ship was moved from Toronto to Hamilton a few years back and I do not think they were side by side in Toronto, but I could be wrong.

I had pondered awhile on the propeller orientation, and had contacted the museum about the display, unfortunately no response.
There is no question that the orientation of the 2 photos is correct, if the Haida display is actually as it appears on various sites, I am surprised they have made a fundamental error.

They have the props arse about, and the prop on the right is actually the port, the left is starboard.
So far, the Arunta shot is the only complete stern photo to show a tribal in drydock with props intact, here is an enhanced crop of the props, showing correct orientation and blade pitch.

Perhaps a small issue, but if someone is building a full hull model of a tribal, wouldn`t you want to get it right?
All the best

I finally found a photo of the Props before they were moved from Toronto to Hamilton. They were indeed switched around when moved. The Shorter one is closest.

Regarding making an Error, keep in mind that the only reason the ship was saved, is that a few sailors took it upon themselves to purchase and move the ship to Toronto. It was cleaned up and kept going by volunteers for many years. It had weapons and gear from WWII mixed with 50s and 60s mods. Even the number painted on the side was her WWII Pendant on top of the Postwar Grey. The guys looking after her weren't too interested in whether the props on display were oriented correctly. Heck, they weren't even the same height!

When the ship was fixed up and taken to Hamilton, efforts were made to keep it accurate to the 50's, but still some mistakes were made. I doubt anybody knew which way the props were supposed to go.

Guys:
I've been struggling with RN colors to paint Haida in 1944 - Im sure this is common !

Munro plans states 3 colors:
'Off-white' - obviously RN off-white
'Mid grey-green' - which must be G20 ? Wouldnt be the 'warm grey' G45.
'Pale blue', - which must be B30 ? Or is it B55 ?

I know that these ships were painted 'Special Emergency Fleet Destroyer Scheme' which is typically G20, G45, B30 & white. Most models of Haida are painted in a 3 color scheme looking like G20 & B30 & white.
Question is, why was Haida painted in just 3 of these colors, not the standard 4? And what were the colors? Maybe her scheme was a one-off?
Any comments are welcome

Going back, the Haida props orientation question may go someway to be answered, by the reply received from the museum.

The props are 10 ft 6" in diameter and have a pitch of 13 ft 1". The prop as it is on the jetty is seen from the hull side not the cone. Going forward, the tops would turn towards each other. Not entirely sure which position is on the dock for port or starboard.
Team Haida

Also, going back further to the DCT discussion, further investigation reveals my incorrect identification of DC stowage racks on Bataan.
These were in fact, squared balsa carley floats, to put the record straight.

Ciao to all,

For the HMS MOWAHK, the armament remained unchanged in 1941 or had it undergone modifications and had the radar on board?

Thanks
Giampiero

I am building the WEM Eskimo kit as HMS Tartar in mid 1944. I have several photos of the ship and it appears that the original fit rangefinder was replaced by an HACS director. Can someone verify that this was done, my research found no information. If an HACS was installed, what Mark director was used?
Thanks,
Doug

In 44 Tartar`s rangefinder turret was a MK II W, her fire control was the later Mk 285 array which consisted of 3 parabolic reflectors each housing 2 seven element yagi booms. If you look back in the thread I have posted a couple of shots of the array.
Her earlier 285 array in 41 consisted of 2 double and a single central reflector, they were a different setup.

The attachment shows her 285 array, and damage sustained in 06.44 action., by this time she had been fitted with lattice foremast.
She is fitted with a 291 X antenna atop the masthead, the smaller parabolic RDF looks like a 268, the image also shows a 253 IFF hourglass antenna.

If you are pondering what the circular objects are on the main yardarm?
They are lantern hoods fitted over the fighting/signal lights to help conceal their illumination from the air.
Many ships by that time had been fitted with these lantern covers, including lower shades, see the attached image.

Closer study of the 44 image reveals she was also fitted with a 242 IFF antenna.
Most ships by that time were fitted with several different IFF aerial array.

Thanks Brett. I will make a director and radar array to fit on the rangefinder tower part of the kit.
Regards,
Doug

While researching where to end the antifouling and paint waterline marks for my restoration project of a scratch built 1:72 HMCS Athabaskan, I dug these out of my father's drawing tubes. These are portions of drawing 3S Docking Plan specific to Athabaskan. Scale is 1/4" to 1'

The bow drawing is of interest, I had previously pondered the circular equipment.
Separate to the retractable 144Q Asdic pod, some Tribals were fitted with them, while others were not.
The Australian ships Arunta and Warramunga were not fitted, but Bataan was.
The use of the word `Oscillators` would indicate `Fessenden` diaphragms, and A/S could pertain to `Acoustic sweep` for acoustic mine sweep.
But A/S could also relate to Hydrophones, Can anyone provide more detailed information?
