Thank you Mark and Scott! I do like the conjecture that they may be Star and will spend some time following that lead. I don’t have Don’s catalog reprint and appreciate the check into that. I’ll spend some time focusing on Hillebrand and Wolf on the patent pages and see if that yields any results. It appears they took over the company in 1869 from Conrad Liebrich. I’ll also try some searching on JMV & Co. more localized to the Philly area, may help. Scott, what year or years does the catalog reprint cover? Thanks again, Bill
