What kind of rims are these?

Hello everyone- I have a 67 912 that I picked up as a project. The car is in sorry shape and needs everything. The car came to me with this set of wheels (15x6?) that don't look like anything special to me; luckily I was selling some parts to a guy that saw them on the car and remarked that they looked like magnesium- I tested the wheels against white vinegar and they do indeed look to be magnesium. The wheels don't appear to have any damage and hold air. What I have been able to see is that there are ‘BB’ stampings on all 4 on the outside rim faces. On the inside, two have ‘B3 85’ and the other two have ’B3 (maybe B6?) 85M’. Anyone know what these are? Are they anything special? Thanks.

I can’t see any other markings. Could these be minilights?

Might well be Minilite Sport wheels. See this thread, especially the post concerning the flat or ball socket lugnut seating differences.

Thanks, Bill- I looked at the link you provided. Definitely looks like what I have, but appears to be aluminum (maybe a different casting run) due to the shinier color under the paint.

It’s always hard to determine accurate color on internet photos, but your first photo shows a weathered area on the hub mounting opening that looks like oxidized magnesium. Also your wheel lugnuts seem to be a flat mount (as opposed to ball or cup mount) which a poster on the link feels were used on the mag versions. You can pour a little vinegar on a bare spot & see if it reacts. If it does, you’ve got mags.
