I want to thank everyone, and there were many, who sent me information on Sharps cartridges to help me in putting together a comperhesive Sharps list.
However, I have stopped working on the list. I have been in contact with another collector who has been working on the same type of list since 1960 and has over 700 notebook pages of lists and information. He plans to publish this information in the not too distant future. I have seen samples of his lists. The list for .50-90 (2 1/2") Sharps alone runs 7 pages!!! I could never hope to equal he information he has amassed in the last 50 years.
So, I will defer to him. I just hope he doesn’t put off the publication TOO long, as he is no longer a young man.
