Below is Mr. Beach's ID of the one in the above thread:
"Von Lengerke & Detmold began to import Francotte shotguns in 1889. You can find a brief history and a list of the models available through the years on my post in the FAQ section.
http://www.doublegunshop.com/forums/ubbthreads.php?ubb=showflat&Number=229207#Post229207 The shotgun in the original post appears to be a Quality "I" (not to be confused with the Grade No. 1). The characteristics include: light weight, Anson & Deeley action, Treble-Fast locking system (Purdey-type double under-lugs, an exposed Greener cross-bolt through a parallel rib extension), and intercepting sears. Most of the catalogs of the period describe this model as an ejector gun but my notes indicate that it was also made as an extractor gun as well. Right now I cannot locate the source of this except for the general statement in the 1896 VL&D catalog (page 12) which says that the lightweight models were available "both with and without automatic ejectors". As the basic lightweight model, the Quality "I" was likely the one to be most readily available as a non-ejector gun. One thing that appears certain is that the features of the particular models were not hard and fast. Just as with gun manufacturers today, models were changed as necessary to meet a price point or incorporate some improvement in appearance or function.
The serial number 20169 is too early to be recorded in our No. 1 VL&D ledger which was created in 1900 but a VL&D advertisement published in 1894 lists several Francottes that were being offered at reduced prices. Serial numbers 204xx, 206xx, 208xx are listed there along with 223xx. This suggests that the OP's gun, number 20169, was likely made between 1889 and 1894 but exactly what year I am uncertain."
