After more peering at the available photos, I replaced the .50 calibre on the back of the turret by a better one:
A very old, already painted one from Italeri
Partly because it's impossible to put the Tiger Models gun in the transport clamp (which isn't on my model yet), but also because that Tiger Models gun is in a special cover with zip etc. while on the well-known photos from Okinawa, there appears to be a simple tarp over the weapon, with that transport clamp over the tarp. (This gun is still loose too, by the way. It's "better" because it will get covered up completely, and for that I prefer to use a part that's as poorly detailed as possible yet still of the right shape and size.)
Making the brush guard over the gunner's periscope was a "fun" job. It's about the same size as the others, but the legs are completely different. For strength, I first drilled holes and glued overlong pieces of brass rod in them:
Next to the turret is the rectangular part that will go horizontally between those legs. After the glue on them had dried, I bent the legs inward and glued the rectangle between them:
Though that sounds
far easier than it actually was … If I had better soldering skills, I think I would have done well to solder the legs to the rectangle and then bend them to fit the holes I drilled in the turret. But I can't solder all that well, so I had to use superglue instead. Once that has thoroughly dried tomorrow, I'll cut the legs down to the level of the rectangle.
It may appear like the rectangle is leaning backward, but that's an optical illusion in the photograph. It is actually horizontal relative to the turret roof.
I've also made an antenna:
The base is by MIG, 3D-printed. I drilled a hole into it at both ends: in the top for 0.3 mm spring steel, 52 mm long to represent two antenna sections, and in the bottom for 0.8 mm florist's wire which will go into a corresponding hole in the turret roof. That 3D-printed resin is not a nice material to drill with a bit as small as for the antenna, it's pretty hard and you can only go very slowly.
