I also wonder why this was not authorised at the end of 1938. I mean, Brüx is in the Sudetenland. The Bohemian name Peterka also points to this. Is that why it took so long or was there a lack of documents? One can only speculate. Probably not, if he had already been involved since 1930.
The numbers and the name are absolutely contemporary and beyond all doubt. Someone has really endeavoured to make the lettering beautiful.
Sure Garry, I can. Um, it's a he, though
