Scubapro Mk25 Ti Alloy no serial number?

[Vq-1]

I have a Mk25 Ti alloy but the unusual thing is that there is no serial number on the regulator but there is a band under the bumper that has number, is that the serial number?
If anyone has anymore info to share about this regulator it would be much appreciated, thanks in advance.

Aren't these the military "no-service" units?

Don’t know, interesting question though.

Never seen one before. I'd be curious to know what you have there, and if you'd be willing to part with it???????

The number in the band seems ti match the SN format — a shot in the dark is it’s a Beta testing batch, or a Mil unit as suggested

I think I have the schematics for that revision (maybe even a info/service bulletin); I’ll check when I get home
I’ve always wondered what was the difference between the TA and T versions; this looks beautiful

@rhwestfall my thoughts exactly

@Vq-1 fogive the very grainy screen capture -- here is what I could find on the materials:

and here are rev C &D for the schematics, I see no real diff against the "normal" Ti version:

Just guessing, there was a time when SP made ultra lite first stages and if memory serves there was a very short run of this early ti attempt with mixed alloy parts. The flashy knob screams “not military” to me. Not stamping into the body was likely for a perceived problem with distortion of something like that or maybe being able to disclaim involvement
