There is only one show in italy which im glad to visit , got this awesome thing i was missing!! its a 8,8cm pzgr with KPS (correct?) driving bands, in quite great conditions. Now, as far as i know on the panzergranate, the big number stenciled below the penetrator should be referring to the explosive charge, that is 92 on the newer pzgr, so what kind of explosive charge was number 28 referring to?
