Might be worth a fortune....
Welcome, and please show us what you've made with that special rule.

I did contact Starrett & was told that their warranty is only good for a year-grin. They did not think that they would have any history about a batch of scales getting engraved incorrectly. Yes I do want to keep the old one.Exactly!
Sell it on ebay as rare one of a kind!
Try sending Starrett an email & see what they say. Perhaps they might send you a replacement? But if they ask for the old one back I would refuse but that's just me.
