My earliest is from 1976 and is done in the characteristic scroll that we so often see from Colt during the middle 1970s through the early 1980s. While I can not confirm this, it seems to me that the Custom Shop produced more engraved Pythons during this period than any other. I do not have photos of, nor can I recall seeing a factory engraved piece earlier than about 1975, but surely they exist and perhaps someone will post it here.
