For Sale: 151BCD Campagnolo Pista Crankset 165mm 49t

I have the following Campag Record Pista crankset for sale. They appear to be made up of a mis-matched set of crank arms. The drive side is 151BCD with just 165 PISTA stamped on the back, and the non-drive side has 165 PISTA. They're both 165 anyway and I've priced them a little less than a matching 151BCD set would be sold for.

Campagnolo Record Pista Crankset - 151BCD
Complete with 49t, 3/32" Record Pista chainring & Campag dust covers. Chainring bolts are unbranded. The cranks are in very good condition, with just light surface marks and with some type of scuff on the non-drive side crank arm.

Price - £150 without Campy dust covers or £165 complete. Will also split and sell the crank arms only for £135.

do you by any chance know what year these are from?

Sorry I can't narrow the down to a specific year.

c20th century

hmm, ive been doing some research coughgooglecough and i thinking they're probably a bit late for my purposes, 1960-7, sorry
have a bump

i have recently acquired a set of these, mine are only stamper pista 165, whats the go on date referencing them? or is there just a 19xx-19xx window?

yea as far as i can tell its a window from 1960 to 1967, although its not 100% clear.
i'm unsure about the exact introduction date but it does seem that 144bcd got introduced in 1967 so these are probably earlier
