1st stage identity

[barneyboco]

I have been scanning for hours without answering my problem.....please excuse me!

Recently received a set of Scubapro regs as replacements stuck in Hurghada!
Is it possible to identify 1st stage from serial numbers e.g. 01077 01016?
Thanks

A picture is worth a lot of numbers

MK-20

And I think the first two numbers of the serial are the year manufactured

Since there is an S600 with it and since the early MK 25 looked like the MK 20 could it be a 25?

Many thanks for the info .... really appreciated

Most likely Mk20. I don't remember seeing a swivel cap on the early Mk25s; I had a set of the early Mk25s and they didn't have the swivel cap. None of the Mk25 schematics show the swivel cap.
