DWM Alphabet Commercial
 

Been asked a question that I couldn't give a good answer to. Could someone give me an approximate date of manufacture of DWM 8317i? I've been guessing 21 - 22. Thank you.

According to Still'a book, 2000i was made middle of 1921. Then K's started 1922.

Thank you very much. So much history.

I read this thread with interest, as my DWM serial number is appox. 800 earlier than the OP's. Thank you.
