Great piece of sculpting Carl, I like the version with the bonnet, just a small point though, I think this type of grenade was only used in the early part of WW1 a while before the British steel helmet was introduced in 1916 and by then the well known Mills Bomb had been in service since 1915, so maybe the steel helmet version is under question with the early grenade, like I say just a small point, I may be wrong I suppose they could have used the early type of grenade later on in the war along with the Mills,who knows? anyway it's a superb sculpt and he looks just as good with the tin hat too.
Cheers
