Help! Can you identify a regulator first stage from its serial number?

[DanMont]

I bought a set of regulators second hand and am not entirely sure what model of first stage I have ended up with! I am pretty sure it is an oceanic (dust cap for the din fitting is marker oceanic)but has no other identifiers other than a serial. So can anyone let me know how I would find out what make/model first stage it is using the serial. FYI the serial is 0001242330. If there is no luck I will try and get a picture on later today.

Without a picture will be pretty hard if not impossible to identify. Yes, a picture will help.

Looks like the first stage from a Delta 3 but I'm not positive. If no one can help try posting over on Oceanics sub forum.

Thanks for the info - with the nudge in the right direction it looks to be an oceanic dx4 first stage. Bit older than I thought it would be but shouldn't be an issue, glad to see it is environmentally sealed. Can go about getting it serviced now I know what it is!

Thanks again!
