Was going through the closet and came across some first stages, I cannot ID. Looking fro some insight from the community.

First Unknown (Pictures 1-4):

1st stage has 1HP, 3LP. Has a stamp on one side: N 36 and the other side: B62787. Yoke knob is stamped: Made in USA (a rarity!)


Second unknown (Pictures 11-14):

1st stage has 2 HP, 4 LP. Swivel lower for 4 LP. Cap on HP side has two opposing dimples for breakdown tool for service access. No stampings at all.

All help is appreciated greatly.

My WAG is a Voit (MR 12) for unknown #1 and a MK 5 clone (not original SP) for #2....possibly a Tekna.

I would bet Nemrod has one of each and probably Greg Barlow too. This might be a good question for the folks in the Vintage section.
 
First is a Voit SwimMaster MR-12 circa 1973.

Second could be any of many, ScubaPro, Oceanic, Tekna etc. I'd bet, based on the yoke screw: Tekna.
 
I'll second the Mk 5 clone is a Tekna based on the yoke screw, the plastic saddle, and what appears to be a curved seat retainer. It's not a straight up clone as it takes thicjer seats than the original SP and the Oceanic clone.

The caution here is that the Mk 5 was probbaly the most cloned first stage in history and lots of companies sold licenced copies or reverse engineered knock offs.
