The 12A and GSL-SE OMP's are not interchangeable. Different bolt locations in relation to the "drive" shaft. The omp delete plates are also different for the same reason.

They were made to replace the stock OMP and pull 2-stroke oil from a source other than the engine oil. You replace the stock omp with this and mount a bottle of oil under your hood so you're not sucking dirty used oil from your engine.
The stock system is the easiest for the average car owner to live with day to day. Just let the omp suck your oil from the engine and never wory about it (!). It actually works fine for 99% of cars.
But lots of rotary car owners prefer to pre-mix and leave the motor oil in the pan where it belongs. I'm one of those guys and removed my stock omp(s). I pre-mix every time I go to the gas station. Better for the engine (in our opinion) but a royal PITA.
This device fixes that, so you have a separate jug of dedicated 2-stroke oil under your hood and don't have to F-around at the gas pump.
It was actually designed and marketed for aviation purposes. The inventor and producer is a pilot and decided it would be safer to suck the lube from a dedicated tank, than to suck his precious engine oil out of the engine while flying cross-country. He told me he stopped making these because nobody is using 12a's and early 13B's any more for light aircraft: All the remaining rotary aviation guys are using the more modern engines (FD's and RX8 motors) and he still makes those. He told me to make ONE for me would cost $500 -800, where he used to be able to have a 100 made at a time for about $30 each from the machine shop. But the market dried up and it's not worth it to make them anymore.
Sad, like so many other makers of parts for our classic cars.

so dose this mean you are selling the other 3? Or you just showing everyone? If your selling the person who started the listing would like one and I would buy one also. But if your just showing us that’s cool, any chance I could get one to copy? I have a sherline mill.

Sorry I wasn't clear (it was late). Yes, 3 of the 4 were for sale. The other will go on my car. @rx7milton and @Endefreshes7 have each asked for one. The last one is still available. PM me if your interested.
I think it would be great if you could reproduce these, but you might want to talk to a patent lawyer to make sure RA can't sue you for reproducing their design.

I contacted them and got the information.
So they said they don’t want to invest in the minimum quality order from the machine shop at 50 units. I think it’s not something they would get mad at you producing. I talked to the person who can support supply and make the orders not the person who invented it. That person is a pilot and I’m not to sure he is into keeping it from the world. They said they sold 5 a year on average so that mean it took them about 10 years to sell the minimum quality order. Since then they supported a few generations of 13B

favorite part is the girls socks in the kitchen lol. Reminds me of my girlfriend she puts up with a lot of silly stuff like transmission parts in the oven and bearings in the freezer in ziplock bags. 2nd favorite part is the progress! Good job! Finally you didn’t hurt your self :-) my person rule #1
Good thought on the patent situation. So far I found a patent for the actual omp, but have not found one for an omp adaptor.
