Thanks for showing these, Dan!
I think Thojil has mentioned once that caliber 740 was manufactured by Lavina which I think is absolutely correct. Like a couple of models in the 7xx range...
Caliber 740 is in my eyes based on this Lavina design from 1908 which has been available in different sizes:

The mentioned US Patent by Edward Staehli from 1904 shows that things does not exactly have to look like in the drawings, it is the principle which is worth the patent.
