I just recently add a 57mmHEAT round to my collection
I swapped a naval 1,1 inch round and casing with Fausto
a BOC member. I thought I would never would aquire one having only seen 2 at the guns shows I have attended and then the price was far more than I wished to pay
I really enjoy this site and hope to do some more swapping trading buying selling here
