Ok, no luck yet on the possibly French proj so I’ll try this one. It appears to be a Russian 47mm drill round. The case is of brass construction and the projectile would appear to be solid or very thick brass. The primer socket appears to have a bolt holding the projectile in place. But its condition is near mint. Can anyone say more about this item i.e. is it Russian, is the projectile genuine in your view and what era does it come from?
many thanks as always, Dave
