[#40]Hello Roger,
How I wrote, I'm nor a "Strubel"-expert, nor I own a "Hermann"-handbook! My stamps are all classified by (different) experts (some with attestations)! One of them is a friend of me, the others are professional (official) swiss experts. I can't help you! (My special theme are the "Numerals"!)
Read (if you have the possibility) the handbook and especially the parts that Heinz 7 names in
[#43]!
I wish you a happy new year!
Andy
