Stanley No. 244 mitre box parts

[rwlasita]

I bought the above mitre box right before our move north and finally got around to cleaning it up and putting it together. What the seller forgot to tell me was the swivel arm was broken. I tried some JB Weld and it seem to hold but when some sheer order was applied, it gave way. All other parts are there and in good condition. Does anyone here know where I can get parts? Not sure thre is a hop in my area that would/could weld this parts. Thanks for your help. Rick
