Mike is right in the numbers of stiffeners. They can be 7,8, or 9 depending on ships,sizes and shapes vary from ship type to other types. IJN did this obviousloy for strengthening against hull deflection. Deflecton rate is so different from ship to ship. They say the largest deflection occurred on non-ribetted ships,the cause of nr.4th fleet accidents...

My bad, on the side of the ship, adjacent to the stacks are 6 panels that run from just aft of the tower to just under the rear torpedo tubes. They sit just above the armour belt.

I was wondering if they were hatches for coal/oiling. Does that make sense?

Looks like a riveted butt joint to me. I would guess there are more than just those four. http://d2vlcm61l7u1fs.cloudfront.net/me ... QShYba.png

Similar joints can be seen on Naka: https://upload.wikimedia.org/wikipedia/ ... r_Naka.jpg

Salvaged off Mutsu. Thx for the comparison.

I've found a nice photo of salvaged 140mm on NavWeaps:

Rainbow seems to have done a much better job with this detail.

I only have a side view drawing. I believe the gun is a 50 Cal Type 3 14cm. The breach was a screw breech. You could search for the gun type.

After Matthews recommendation I've ordered the resin shields, and those are really fine. A nic addition to my Hasegawa Tenryu, even in deluxe version Hasegawa doesn't provide us with any add-ons for the shields.

I compared resin gun breech with Hasegawa's plastic gun, and it's interesting to see that they have completely different shape, Hasegawa being round and Rainbow being square-shaped. Are there any gun breech photos to confirm the shape?

Another thing is this weird photo-etched...frame around each shield. It is marked as an optional addition, but I haven't seen such thing in any picture of those shields in reality. What is this supposed to be?

Hello guys,
I've just recently discovered wide offer of Rainbow Model accesories, and I'm very interested in their two versions of 140mm guns:

Both sets look great on their page, but has anyone used them already?


I have the Rainbow Resin Gun houses for the 140mm IJN guns on their CLs.

They are really nice. Now if I could just finish building the danger bridge for my Nagara.

Hi all, totally agree about Rainbow. But no, I used the default Hasegawa guns (just making the sides and roof more thin from the back side) + brass barrels (from the very nice Five Stars PE set) for my Tenryu. I considered the Rainbow options for the old mold Tenryu, but then Hasegawa launched the new mold which is ways better. I would definitely go for them in case of older light cruiser kits though.

In general, I find Rainbow to be an excellent source of accurate PE. I have the barrels, but not the entire turret.

Perhaps Vladi used them in his recent Tenryu build - I haven't checked.

Circular bases did exist for permanently mounted 25mm singles. It's hard to find a photo from above that shows a mount on its base. This photo of Yukikaze postwar clearly shows the remaining mounting rings. See also Report JM-200-F 0-47(N)-2 on AA machine guns and mounts: http://www.fischer-tropsch.org/primary_ ... MJ_toc.htm

OK, so no answer there! Next, the single 25MM type 96 guns. I cannot find a photo anywhere of one with a circular base (that seems to be fitted to so may kits in the form of deck molding. I'm just not convinced a circular base is right. Is it a case of aftermarket following what's on a kit to make it look better. I thought they were square or just bolted in at the pedestal.

Kiso and Kitakami never received a catapult with their first modernizations in the early 1930s, unlike the other 55000 tonners. Something to do with limitations under the 1930 London naval treaty.

Kiso had, when she was new, a hangar in the bridge (in contrast to the other Kuma class ships) and she had a launch platform in front of the bridge, which was at least tested. She did not got a catapult and therefore had never floatplanes (only Kuma and Tama got catapults). The hangar was removed before the war. According to Japanese articles, she probably got a 13 mm twin in front of the bridge in the place of the former forward extension of the hangar.

Dan and all,

I'm getting the impression from Kiso's TROM at Combinedfleet that she never had a floatplane or catapult fitted, even pre-war. Is my guess correct?

Her bridge superstructure is also quite different from the rest of the Kuma class.

Here's a gallery at another site that showcases Kiso in her Aleutians camo to inspire anyone to build the 1/700 Tamiya kit.

I dunno. That would be an awful lot of scupper pipes. It's clearly a busier hull than I'm used to seeing.

Something that I noticed....

Every one of those "Panels" has what looks to be a drain-pipe hanging down from it in the same place.

Could that have any relation to what they are there?

I don't know if they were "welded"--I did not use that term--or if they were to "stabilise" the hull, but was thinking of the Ducol strakes added onto ASHIGARA, for hull strengthening. But, I'm just guessing...

ISUZU did suffer hull damage on multiple occasions during the war from direct hits & near-misses by bombs and also by mining.

Also, during her final May-Sept 1944 refit "...the scuttles on the lower deck side were sealed to improve watertight integrity..." (per L&W's CruBible, p. 402)

Those excellent close-up images seem to show no external degaussing cable. Were they internal after her last upgrades?

I can't say for sure, but some sort of strengthening strake makes the most sense to me. The one surviving 5500 tonner was Kitakami, but the postwar photos of her aren't clear enough to make any sort of determination.
