The 7451 is the only item that could be a date code..year 1974 week 51.
If they are screw mounted they are probably computer grade, I just dont
recognize any currently used part #.

I would not recommend them for amp service, way too much
capacity....20-25MF total is sufficient for SSB/CW service.
If you do use them I would bring them up to voltage very slowly and
monitor leakage current.
