Any ideas on replacement part?
 

I had an accident with my machine cleaning and my son knocked over some parts, now I cannot find the bearing for the needle bar. It is a Davis Minnesota model E, dated approx 1902. Any ideas on replacing it?

I would read through here Sears Roebuck and their Sewing Machines (ismacs.net) to see what other Minnesota machines were made by Davis then start combing through ebay for parts for whichever Minnesota machine might have a part that could work.
