Thanks, so much, Carolina Reb:

Your first hand work speaks for itself and helps me a lot. So far, no one else has responded. I am PM'ing other Spencer buffs and will add what they indicate. But I expect they will confirm your info.

Rather interesting and perhaps Sharps experts will know if Sharps did this. C. Spencer was close to the Sharps company, at least in the early years. After over ten years of Spencer reading and questions being answered authoritatively by others than Marcot, often with photo's, hardly a month passes without a "discovery" not mentioned in his book. Not criticizing, but I imagine that a few experts out there could get together and write a fascinating supplement to Marcot.

You made my day!

All the best,

Kevin Tinny
