I recently found (and purchased) a Francotte SxS from a local tactical shop that had it on consignment. It has the Von Lengerke & Detmold in the top of one barrel.

SN# 28011

The database would suggest that it is a 1896-97 Medium Grade.
It is well used and the wood isn't in the greatest shape.

I have not taken possession of the gun yet but found this forum when searching for information.

I was hoping someone might be able to shed some light on this!

Thanks for your help in advance
