Oil Tank Identification

[dennisv]

I would appreciate some help identifying these oil tanks. I've done quite a bit of research and have labeled my educated guesses. Can anyone confirm or correct?

I am working on an engine test stand and will pick one to use for that. I am thinking the one bottom left is the best candidate. It appears to be the least valuable, has fewer ports to deal with than the one bottom right, and a couple mounting points built in.

Thanks.

Go to posts 6 and 13. The bottom right would have least value to collectors.

Thanks for that link. It is helpful. I'm still not clear on the part number. The PDF catalog for 74-78 and 78-83 list a few with the same drawing but don't differentiate them:
930 107 006 00
930 107 006 03
930 107 006 04
930 107 006 07

I think the two additional ports are an indication this was meant for Sportmatic.

The one lower left, labeled 73-77 is a 73 one year only.

Not Sportmatic. It is from the '80's and probably for the 930 Turbo models.
