Older Catalina Cylinder Markings

[Scott]

I have a couple cylinders that are missing manufactures markings and the model doesn’t fit the pressure ratings.
Currently Catalina 3000 psi cyclones are stamped SXX, XX being the rates capacity and 3300 psi begin with C.

In the nineties, or prior to, did Catalina make an S70 rated at 3300psi and a S60 rated the same.

Another oddity is there appears to be no original hydro stamp.

Catalina made "super 80" tanks and Al tanks rated at 3300 psi which were 100 cf.

I knew about the 100cf @ 3300 psi, but these two are neither. One is S70 and the other S60. the 70 is a bit shorter than todays S80.

Perhaps early versions before the they started using the "C"??? Here is another S80 @ 3300 psi (flea-bay #154748161594). It is also from 1989 - that hydro is the original hydro. On your two cylinders the same, the 1989 date is the original hydro.

What throws me though is the RIN IA11. I have not seen that numbering before. Catalina's current RIN is C707 which would be seen as:

C7
70

I would send Catalina a note and ask about their history: sales@catalinacylinders.com

Thanks for the flea-bay and Catalina link.
