Margaret I bought one that I thought was hopelessly frozen but got it freed up with the usual oiling, wiggling, and hair dryer application (lather, rinse, and repeat!) Just need to get the cam assembly re-installed and give it the all over oiling before I put it on the sewing table. This model is among the royalty of the vintage sewing machine world so I wouldn't hesitate to get it if it was in reasonably good condition.
