Hi Pat,
Thanks for those links, excellent viewing. Being British Shermans I think it's quite possible they had tie downs on the right. The M4A4 had a smoke discharger thing on the back, which I believe is what that odd box affair is and units were inclined to have their own SOPs regarding vehicle stowage.
From past experience it was quite common to take your vehicle down to the LAD and get something added on if you got on well with the SSgt and bought him a few pints in the mess, all things are possible.
Anyway, we shall se what else turn up before I get the knife out and remove them. I think the number would depend on what was available when the vehicles were being kitted out in the Wksps. If you get to the last 10 vehicles and don't have enough for 8 then you probably fit 5 or 6 whatever is available.
The smoke dischargers do look cool, I have hopes to do one like that yet.
Re the welds I looked at the links you posted, do I need to do them on the front slightly sunken sections also? Hadn't thought about that.
Thanks for the feedback - great
Back to some Sherman viewing then,
Cheers

PS did you pick up on the Skink Sherman AA - very unusual.
Edit, there's an interesting example in there with a large steel plate welded over the front.
