Today, after a long talk with my friend Manncarc we found a real conclussion: in post #30 I say that there are two models of Brixia: A short one and a larger one, well, I said this looking the mortars found here in Spain at the battlefields, this is not true: the standard Brixia is 132mm from base to top of fuze cover, the shorter ones found here were from SPANISH MANUFACTURE, the Blue, National, Fascist or Franco side, (as you want to call it), made their own projectiles, HERE the difference. More: As fert says in post #6 you can find one difference between some Brixias: the explosive contanier, (where the frag coil goes in); not the outter body, made of Brass or Aluminium. In Spain both containers can be found at battlefields, BUT none of the fins found with them are marked, no date nor model. All the Brixias I have seen or have in my collection had the fins marked always with mod39. My pal and myself found interesting to post this info for the rest of members, so here you have it. The brixia mortar is an easy to find item at fairs, but it has a larger and more interesting history than many people think.
