Suffolk Punch Professional

Dear forum!!

I am in the middle of a Suffolk Punch Professional re build and have realised I am missing 2 parts. I am asking for help to try to find a place I can purchase the parts required.

The main cutting cylinder runs in a ball bearing at each end. The bearings are pushed into the cast bearing carriers and then a steel cap sits against the bearing in between the bearing and blade. I think it is to help keep grease in and dirt out. The steel caps are not flat. The internal hole is pressed/shaped to fit slightly over the shaft. 

Can anybody help?? I need a pair of these steel caps. Anybody know where I can get hold of them?

Thankyou for your help!!
