My mind is reeling !
But this is one thread I shall refer back to regularly.
I'm starting to wonder about the comparison between German 20mm cannon and Hispano - but I think I'll leave that for another thread !!
I'm very interested in the 30mm
gun, though. Not very much seems to have been written in English about this weapon....
And Erich , do keep us posted about your 'digging' adventures - I for one am happy to read anything at all about aviation archaelogy.
