These stampings with the SiBronze in the them are tiny. Not the same stamps.Also, I used a straight edge to find out where material had been removed for the frame number and there are no irregularities.Further, I stripped paint from my 1960 G9 and found numbers in the same area as these little numbers. They began with M12 and then a longer series of numbers. There is also some kind of a logo in an oval. So, they are all there from the factory. (except the P11 Frame number, which must have been added)I wonder if my P11 frame was an unnumbered replacement frame and someone just stamped it to make it work with their loose Commando motor.
