While a PST HP149 existed on paper at one point, there were production problems and it is unclear whether any were sold. Based on some comments I've seen, I believe the problem had to do with press capacity for one of the required tests for each lot that required a cylinder wall to be crushed over a corner of a certain radius.

None of the lists of specifications for Worthington HP cylinders seems to mention an HP149.

Does anyone know if there are any of these cylinders out there?
