I just got a pair of Faber lp120's. Many will call them 121's or be listed as 121's but hold 125. The only physical difference in them that I acan see is that one tank has factory XS Scuba stamped in the neck and the other does not. One tank has REE code of 97 and the other has 98. These 2 tanks make 3 of these creatures i have the other one has OMS stamped in the neck. Are these tanks actually the same but have different markings because of the distributers name being stamped on them. I also own a pair of LP 95's they have SEAPERLS stamped on them. When i got them i was told that the only difference in a faber and an oms faber was the anticorosive coating in the tank. So Is not a faber a faber a faber?
