Great catch. Very exciting! I thought for a second the 4 tube rad was a Republic Oriole, but it's not. Maybe the convectors though? We'll see.

I just finished reading "We got steam heat" by Dan Holohan. It's a great read and I was chuckling all the way through, but most importantly it gives a great description of steam systems, their components and how they work, all in simple terms (for guys like me:). I learned a lot from it.
Thanx for the suggestion, I would recommend it to anyone new to steam

For the convectors, the stack height is important to determine the rating. It's measured from the floor of the enclosure to the top. See below. If you can't find any writing or identifying marks/symbols anywhere, then I would use the following to approximate:
Arco Convector No. 5, 28" L:

You can also use the OCS sheet that was posted earlier. If the stack height is between the listed values just interpolate.

I dont have the stack height on hand, based on the following picture it looks like it is 17-18. This picture is measuring the outside of the enclosure from the floor

Looks like 18.5". So using Arco that would be around 25.3 for each convector, putting you at 455.9. If you use the OCS ratings, it would be about 21 I think, so 443. Burnham STMX 175, Williamson GSA 175, Weil-Mclain EG-50, Peerless 63-04…They all fall right around 450 it seems and should work.
