As to the original question, the Francotte was received in inventory at Von Lengerke & Detmold on January 26, 1901. The model was the Grade 'BB', a sideplated boxlock with ejectors and "Quadruple Wedge Fastening". The Grade 'BB" sold for $200 until the models names were changed and the number of models were reduced in 1910. The Grade 'BB' then became the grade No. 20 and in 1923 it became the grade No.25 as the models were further reduced. Francotte 33750 was transferred to VL&A in 1901.
The same shotgun was consigned for sale at A&F in 1956 and was sold in 1957. Further information is available if Geb will contact me.
