Lloyd,
Francotte 70099 was received at Von Lengerke & Detmold in NYC on December 22, 1909. The model is recorded as a Grade "AA". That model was a featherweight game gun - please see my list of Francotte models at
Francotte ModelsThe post is the eighth one down the page.
1909 was a time of model transition at VL&D. It is understandable that photos of your gun show features that other Francotte owners may question. In earlier years the model "AA" would have had scalloped & checkered sidelock-shaped side panels, intercepting sears and triangular shaped engraving on the barrels at the breech. Also, this model in earlier years would not have had the dimpled pins in the receiver. Here is a photo of a similar Francotte model made in 1901 (actually it is a model "A" which was the same gun but in a heavier configuration).
In 1910, VL&D renamed most of the Francotte models and the models "A" and "AA" became the grade "No.17.5" which meant that, like the "A" and "AA" before it, it sold for $175. This model was dropped by VL&D after WWI.
Your gun was sold in 1910.
