Hi Hoeksel
Hi HoekselThanks AKON! Maybe our Swedish members can help here. Hope to get the actual dimensions and a head stamp!
D/27 is L/27 I assume (and not 1927).
This is perhaps a step forward in the reliable identification of those parameters that we do not know. I am interested in a copy of the book, of courseI think I have good new, I just found out the Dutch army museum has a book titled "Canon d'infanterie de 37 mm L/27" dated 1928 and I found it when looking for Skoda materiels. It will take time, but I will request to check out and copy this book.
