I think Albert was making an estimate of the upper limit of 10000 range Lugers with the pushbutton stock. Kenyon estimates a slightly higher number (10000-10050). These Lugers are a limited production Commercial series that do not have the "B" suffix.

This gun, 10010B, would appear to be a prototype, possibly a precursor to the aforementioned 7" pushbutton stock variation. If it truly is a prototype piece the rear of the toggle should bear the GL monogram. Photos of the toggle rear and bottom of the rear grip strap plus as many interior part photos as possible (particularly the bottom of the receiver) are needed.

When I made the photo much lighter it appears that there is a stock lug but of a much thinner configuration than usual which might be an indication that this Luger also had a pushbutton stock.
