It is a very nice kit.
I took some more photographs last night, the kit is finished (except for the HMG stowage and the bow MG, the latter goes on at the last because it is so vulnerable, the former for simar reasons).
As an amusing aside, I managed to break the ruggedised M2 on the sprue, not sure how, but the early turret lost its aerial as well.
I had left the cupola off, but having dropped it on the floor twice I glued it on. Then remembered why I had left it off, because I needed to remove the M2 mount on the roof - it will have the mount forward of the commander's hatch.
The only things missing are the infantry telephone and the first aid box.
Good idea on the HMG stowage.
