Sorry it took so long to get back, I just got some spare time to look up some examples: RCA #94 and 95. Both of these are early, in the 2" x 5" range, not a lot of curve. In the Schreyer Sr. and Jr. book: #10 and 11. Also the guards on these have a fairly straight rail that stands away from the wrist. Any suggestions on these ?
Thanks, Roland
