@flowert : thank you very much for contacting Paul! I did not know how to do it.
@Paul_K: Thank you so much! Your Paulson’s catalog is super rare, I am looking already for it for a long time.
Actually there is one more Angelus movement which could be in the Paulson and nowhere else: Cal. 123. I do have a picture from cal 123 (from Roland Ranfft) but just from the dial side.
I also would love to compare the 56 with the picture of the 120 in Paulson’s catalog, maybe you can also find this cal. in the book. These three movement calibers are almost identical and all 10,5 lines.
All three were also manifactured by Lavine, possibly in cooperation with Angelus, because just these three are listed in parts catalogs also for Angelus. The later movement calibers, which Angelus used in their watches (ETA, Phenix, AS) are never listed under Angelus in parts catalogs.
The chronographs and their ,relatives" are all already in my picture collection. Just from the smalles eight-day wristwatch-movement and some pocket watch movements I still need the original cal. numbers of Angelus (besides the pictures of the three movements mentioned above).
My article will be published in Klassik Uhren, Germany. I researched quite a lot, also on serial numbers and changes in logo design.
Best wishes and many thanks!
