got given an old 761xl today not one of crosmans finest designs and needs the check valve replacing but this is the Whaley conversion which have a very naff reputation but to me very collectable
I was sent it as I've been putting together a bulkfill co2 rifle like the early 113
but using the sideplates from a 761 and as I haven't many of the needed parts this will enable me to make brass copies of the plastic cocking parts
I know the Whaleys were based on 1400/140 tubes pump levers and valve parts but this has a brass tube and certainly not a 140/1400 lever so might be a custom tube or one based on an earlier crosman pumper like a 120 i'll know more when I rebuild her
