I've been trying to get an overview of Emil Busch serial numbers recently. It seems like the company didn't serialize most of their lenses early on and only started to do so (at least some products) more consistently from 1900 on. They did use serial numbers on their projection lenses, but I'm not sure which large format series even got one. Because the company stopped producing taking lenses at some point in the early 20th century so most of those might have relatively low serial numbers overall, but who knows if they even just used one system or multiple...
Anyway, if you have any Emil Busch lenses with a serial number on them and can share the lens name, focal length and serial number (and if you know because of some coincidence also the year of manufacture) that would help a lot.
Additionally, if you have any Emil Busch projection lenses (marked as such or unmarked) like the Glaukar, Neokino, Mod V. Mod W. etc. it would be great, if you could share that as well, even if they don't have any serial number on them.
Last but not least: If you have any catalogs by Emil Busch/Rathenower Optische Industria-Anstalt in your possession which you can share - anything from 1890 - 1940 is of particular interest - I'd really appreciate it, if you can share (parts of) it. I think I've already managed to find most of the stuff that's already online (at least I've looked around A LOT) but if you know some lesser known spot of where to find stuff, links are of great value as well.
Thanks a lot!
