Here it is! Notice the slight tilt to the right, correct according to Book by D. Sheldon on page 117. also serial number part of 600 shipped to Mexico in 1908. The serial number is 308xx. And man are these fun to shoot!Dadduck, PLease don't leave us hanging! I would love to see how it is marked!
I was thinking about this issue a little. The problem is the spring. If a 1911, or 1905 spring is installed in a 1900 or 1902 I think it would shoot anything safely. The original slide spring is too weak so that the cross bar hits the rear of the frame, or the compressed spring and sends a shock to the slide nose. It may take some adjusting to get the gun to eject properly due to the extra tension but if tuned properly with the correct tension. I don't see why it would not work.
