Joe, I just went over and pulled that scope out of the cabinet, and the serial no. on mine is 22,432. However, that picture you posted looks just like the knobs on my Small Game. The clicker still works on my windage knob, but just barely...the plate's cracked in half and one half has gone missing. If you want to send it, I'll try and see if it fits...nothing ventured, nothing gained, I guess!
Whitey, that Field's Patent is coming along nicely. Shouldn't be too much longer now...it actually went pretty quickly once I figured out how to approach the inletting.
