engraved
The engraved models were serial # 1,000 to 5,000 only. Most had the gold tint (champagne) some had the silver. The gold was a nicer looking unit IMHO.
The engraved is easy to spot since the entire face plate is slightly engraved and the serial number range.
Anyway, if you have any further questions about the engraved 2270 contact me by private message. Good luck with your rebuilds!! DG
