Hi Experts,
Sorry to write in English, but Ich sprechen nicht Deutsch.

Some years ago I got an Alser wood. For the first sight it seems a normal Alser allround wood produced in this period: 1975-1979. The only strange thing is the numberings. It is: 52.
Do you have any infos about the numbers without letters?
I have never seen this number before.
If "A" number produced: 1975, is it from: 1974? Or?
Thanks for your help.
