As I am going British for this I'll have a Heer set going spare - M36 + troos + jackboots + belt + helmet
Sizes? My size. Average height, average weight, above average length/girth.
So, 34" waist shortish leg, 42" chest or sommat and size 9 boots. Can't remember helmet size but it will be 59/60cm or thereabouts.
Also can lend a rucksack lookalike for any Gebirgsjäger player
Scrub that, nothing left to lend now.
Complete longshot here; I doubt anyone owns more than one pair of steingrau trews but if you happen to I'd be much obliged if you'd lend them to myself, even the daintiest of repros tend to be over size for me, so anything considered. Usual Break it, mend it rules would apply of course!
I've fired a bullet on every continent. Nearly hit someone, too.
