Gad! I SHOULD have told you this is the same type of handle found on many garage doors. I replaced the one on my
Scamp a number of years ago. It's now the "T" shape. The shaft was the exact same, except too long. The locksmith I bought the garage door handle from just put it in a vice and cut it off to the same length as the Scamp one I took in for comparison. Even the screw holes matched up. And yes, it also has a key.
SORRY!
