Hi Carl , I believe you have a 1951 "omega" #10, the only year they made those, it looks & runs real fine, I noticed quite a bit of bubbling around the steam chest & cylinder solder line, don't be surprised if the cylinder comes loose....but this can be fixed fairly easily.
Thanks Bruce for your comment since taking the video I have used some CA glue that Roger used
on his great website. The CA glue fixed the problem very easily and fixed the leak.
