151BCD is the original Campag  chainring size from when they first started making chainsets.  Smallest available is 44 (BUT - they did make a few 43's but rocking horse excrement is more readily available).  They altered the BCD to 144 so that a smaller 42 tooth ring (with a possible 41 potentially available as above) could be used.  I also have a pair of 177.5 cranks but they are Pista.  However, I have used them with double rings and I have some 'drillium' ones to suit.  They are fitted with Campag Pista pedals, toeclips and straps.
