Can someone identify this Scuba Pro 1st stage?

[gregorvn]

I bought a bundle of stuff and it included a Scuba Pro 1st stage with a G250 Second.

I can't find any markings on the 1st stage. Can someone identify what model it is for me? There are two HP ports and 4 LP.

Any ideas?

Thanks,
Greg

mk10 spec, missing the spec boot

Thanks for the quick reply. When you say missing the spec boot, is this something necessary that I'll need to replace? Would a LDS have this when I take it to them for servicing?

No, and most likely no again unless the shop has been around a while. The spec boot goes in that groove with holes. It's an environmental seal that holds grease in the spring chamber just like an Atomic regulator. It's not a necessary component and the reg will function fine without it.

Great! Thanks for your help.

In Japan they were sold without the spec boot, there are a ton of them for sale over here and I've only ever seen a spec boot once and that was on a MK10 Plus. Personally, I think they look like something is "missing" without it. You've more chance buying hens teeth from an LDS than a spec boot.
