McQuay coil capacity? It is easy?
This evaporator coil appears to be several years older than dirt.
M. # RLC-200B F
S. # 3302058
Four 1/20 HP fans on it.
Is it as easy as it being a 20,000 BTU coil ? <g>
If not; what is the secret code which reveals it?PHM

Yes, it's that easy.
The capacity is 20,000 Btuh at a 10ºF TD.
If you need parts, go to Heatcraft. The McQuay line was bought up by Snyder General, the RLC design was then under the Chandler brand which is now part of Heatcraft.

Thanks Ice -
It's for a country club's beer box. They installed it all used maybe 15-20 years ago and it looked like something I would have been a little apologetic about giving to the scrap guys even back then.
With 8º subcooling and the R-12 valve wide open it is running about a 5 lb. suction pressure and an 80º SSH. Think I'll try a new valve and see what happens.
Also; cannot get the screws out of the motor mounts - so that will need to be cut off I guess. I wonder if anything like a motor mount is still available? <g>

Here's a link to the Heatcraft Interlink parts listings for Chandler:
It looks like you may have an "F" vintage, but call them and with your Mod/Serial numbers, they should be able to tell you if the mounts are still available.
I know a lot of the very old parts are no longer available.
