I am presently restoring two Reproducos, both of which have had their
pneumatics recovered very poorly.  I am quite sure the span is wrong.
The span on these is close to 1-1/4", and I am sure that span should be
closer to 7/8 to 1".

There is no stop or regulating button to protect the hammer action from
being over pushed, so the correct span is critical to proper operation.
If anyone can verify the correct span, I would appreciate it very much.

Thank you
