Oh where, oh where can I obtain a PIFCO 1104 blade for my food processor?

I have tried to obtain parts for my long service PIFCO 1104 food processor but to no avail. I will be very grateful for any information as how to obtain the chopping blade and the plastic blade. I know it's an ancient model, but the service is excellent and really would like to continue using my dear little pal for a bit longer.

Thanks for any information/help or at least how to mend the plastic on the the chopping blade.
