I'm not particularly familiar with Apeks regs, having only typically used and serviced ScubaPro, Aqualung and Poseidons. I picked up a batch lot of equipment from a retired diver, and it included 5x first and 5x second stages, plus an inflator cylinder first stage. The Aqualung Legend is an easy ID, but hopefully from these pics anyone who knows the Apeks line-up will be able to tell me what they are so I can pick up service kits and clean them up. They all look a bit funky on the outside, and I'm sure they'll look worse inside when I open them up :/

There are two of the polished first stages and one of the brushed. See next post for more pics.

This first stage doesn't have Apeks branding, so I'm not sure it it is Apeks or something else.
Obviously one of the seconds is an ATX200, but the other two?

And then finally this inflator first stage that I have no idea about, or how I go about finding a service kit for it?

Looks like an FSR to me.

I just brought myself a new inflator reg for 800 nok (~70 USD) so not sure Id spend time searching for a service kit for the inflator reg.
 
I have some of those regs so...

As @Alekseolsen said, the polished first stages in your first post are FSRs. In the first pic in the first post the date of manufacturer portion of the Serial Number (0604) means it was made in April 2006.

The two second stages in the second pic in your second post are XTX200s (note the chrome trim that is the difference between them and their otherwise identical and less expensive XTX50 brethren). You should see a model badge on the XTX200s on the top of the reg (near where your upper lip would be if it was in your mouth). As both regs have oval purge buttons, they are of the same era as the FSR I mentioned above (the newer XTXs have purge buttons in a bowtie shape). FWIW, the Serial Numbers on the lower rim of the regs will tell you when they were made...first four number are YYMM.
 
The Apeks satin first stage seems to be an FSR (ATX200).
The Apeks shiny first stage seems to be an FSR (XTX200).
The satin unbranded first stage is a Well Marine Diver FS-808 Ice.
The drysuit first stage is a Well Marine Diver FS-810C.

The second stages are Apeks XTX200 from pre 2011.

Well Marine Divers produces for many (many!) other "manufacturers", so who actually sold them is likely something you won't find out.

Thanks for that info @gratefulmjc. The model badge decal has come off both XTX200 second stages, so was relying on the purge as an identifier.
 
So my next question is, where do I go about finding service kits for the WMD first stages?
