Headstamps are the giveaway.
M18 = 75mm gun, Sherman, Cromwell, Chaffee etc.
M5A1 = 75mm howitzer. These are shorter.
75 DEC = French WW1 Artillery.
The M18 and French are essentially the same case but the primer and crimping differ.
I would be interested in any M18 cases.
I think, for what it's worth, you should go for the 95mm. It was, is a Cromwell VI and it would be good to see one running around. It is harder to do properly than a 75 though as the turret front and mantlet are different than a 6 pdr/ 75mm.
As for a Saladin gun......:n00b:
I was planning to write that I suspected engines were delivered new in sky blue later on but it was more of a feeling than a known fact for me and I've made myself look foolish before like that so I left it out! Nice to have it confirmed. :tup::
Originally, Meteor I and III were a green similar to olive drab when new, eu-de-nil was a rebuild colour. Sky blue became the rebuild colour, I'm not sure when, certainly by the early 1970s but I suspect Richard Farrant knows for sure.
Well it's definately been transformeed which was a post war program so more likely range damage. It was likely an anti tank range or possibly artillery firing solid shot.
