I found a scope on ebay but unfortunatelly the seller couldn't post pictures. He did his best to describe it and it sounded about right according to the dimensions he gave.
The markings on it are:
"A.S.I 4 X 20 COATED IMAGE MOVING JAPAN"
It should be here in a day or 2. Fingers crossed its the correct one 
Even if it isn't I'm sure its a close match and for $7 it can't be bad!
