What is this seal?

Got a pair of these with some other junk from an auction. No idea what they fit, I suspect maybe final drive sprocket seals? This is from a local mechanic shop who worked mainly on Cats though also some other stuff so while I think they're cat I can't say for sure. Obviously used but were kept for some reason, maybe still good?

I'm hoping someone can id them and we can find them a good home - I hate to throw them out but have no use for em myself.

got a part #?
They look like D6 Final Drive Seals

No part number I can see anywhere. May be one hidden somewhere but it wasn't worth trying to scour it clean enough to say for sure.

they definitely look like 4r/5r/8u/9u final drive seals. they are getting close to being unobtainable, cat wanted over 900 dollars a piece two years ago for them, dana at florin tractor had some NOS copper type bellows seals for about 250 a piece.

if they are still good, I would definitely see if someone can use them, don't throw them away.
