Disc brake identification

Can anyone id these discs. I can find no manufacter markings, only minimum thicknes.

Mid 80's AP Racing ???? (Or were they still AP Lockheed then??) They're probably race discs as they look like cast iron gone rusty.

Dezza yes they are cast iron   so could well be.  I shall google ap to see if I can find a comparison.

Could also be PFM discs, they used to sell the rotors with bobbins for fitting onto standard centres

These were new old stock PFM gsxr400…..

Looks like the peculiar pattern of drilled holes is exactly the same!

Sorry baldrick,

   I didn't mean to imply that my carriers were Spondon. My carriers are Kosman, but my calipers are Spondon.
