found this one not working on ebay and with the 123 on it i thought it might be mastered,got lucky and it was.
The other locks always had 5 master levers,this one only 4 and broken shackle spring, do not like taking apart these but it now works good for me.







Did not like taking apart but with a used spring and 3 working keys,i’m good with the results
thought the inner workings might be of interest to some
