Thanks to you both for reassuring me

I know it would be easier to buid one of the 3 GMC kits that are waiting on my shelf, but I can't help looking for difficulties whenever I can...I think I'd better leave this project aside, and stick to something more reasonable, like a scratchbuilt M 39 :-)
P.S. thanks for the pic, Gunnie, but I already have found it. It must be the one and only M5H6 pic on the Web !
