Hey, local yard decided to hook me up with a box of center caps when I went in looking for 2-3 sets. I've ID most of them but a few of these pieces have me pretty confused.
I have a bbs metal ring w/ part no. 08 23 137 w/ the usual bbs stamp & made in w. germany
one center cap marked 09.23.114 all i could find on this was 'bbs custom wheel cap' from some guy on ebay..

Also not sure about the two caps w/ yellowing center, marked m249 on the back. online says they're from OZ ? but no markings indicate that.
one last question. (sorry to spam on my friend post
)
any clue what these are from?
part no. BC 74 5 18
thanks guys for any help.
