Re: Lerebours Serial Number - Rice Writing
Well, I received the P et P booklet covering Lerebours et Secretan. It is at least as comprehensive as any of the other sections I have seen. This is just a short reference relating to things taken up in this thread, I'll come back later with more!
1. Believe it or not- but our French friends have not discovered the micro scratching of seriai numbers on lenses which existed for a long period in the 1850's.
2. The cup inserts we have described here are called "Diaphragme emboite". They date this system as being from before 1855 and the central washer system as post 1855. And Waterhouse stops after 1860.
3. Serial numbers and Dates.
1839 - 1845. no serial numbers
1845. - 1850. 2000 to 5000
1850 - 1855. 5000 to 8000
1855. - 1860. 8000 to 11000
1860 - 1865. 11000 to 12900
Lowest number reported by them is 2012 and highest is 12609!
Re: Lerebours Serial Number - Rice Writing
I think this serial number list will push back quite a lot of your Lerebours lenses to the 1840's!

Thanks Steven! Great info. I was told my lens #7799 was mid-1850s so this confirms it.
PS: what is the P et P booklet?

Re: Lerebours Serial Number - Rice Writing
It is a variety of what used to be called "subscription publication" in Victorian times. Just 100 examples of each dedicated booklet. Obviously the price would less if there was a larger market available - but there isn't! It isn't a profit-making organisation!
A single old catalogue would cost more. The ones I have bought have certainly been useful.

It helps that I speak French of course but yes, it is easy to use the images and the tables in the publications.
Was indeed surprised that they didn't mention the glass engraving with the serial number. (And we know their serial number table is no longer correct for the Hermagis lens ... )
Cheers,

Thank you both, Steve and Rudi!
