Chain ring Campagnolo 48 teeth, BCD 144 mm, 3/32"

Bargain of the week: a brand new chain ring for my Campagnolo equipped track bikes.
This extends my collection a bit.
I need at least an extra Campagnolo 50T and 52T, as well as a rare Campagnolo BCD 151 mm BCD ring.
Note that the price on the tag is not what I paid for it.
Good news: some extra pieces still available!
