Next, onto the portholes. Some of them have grids and I had to find out exactly which ones are true.
The grid would only have had a right to exist at the height of the anchors. On this ship, the anchors were pulled back on board with the davits and an anchor could have hit the hull or the porthole. In addition, the anchor chains ran past the portholes.
So I looked at everything I had in detail again.
The fact is that during active service, here in 1921, the front portholes were barred. You can see this in the following and best quality picture of the ship that I have. It was taken in Vladivostok in 1921.

Here the section is enlarged. So there were bars, but you can’t really tell whether all the lower portholes on the bow were barred.

Then this picture of the stern, also taken in Vladivostok in 1921. So quite late in their active service. She was in this dry dock for repairs.

Here the enlarged and brightened section shows that there were definitely no grilles in front of the portholes at the rear.

So the question arises as to where this protective measure went. The anchor area would be logical. I found the solution in the following picture.

The white arrow points to the same porthole in both photos. You can clearly see here that the portholes were protected with grilles right up to the anchor storage areas.
