Steam Radiator brand identification

MarkZeh

Hello fellow steam brothers, need help identifying this brand Rad as I have a few. Fow reference, 5 tube rad measures 8" in width and 25" in height, 15 sections at ~ 38" in length. Note tap port/point just above the end plug. Looks like 1920s to 1930s styling similar to Arcos. Top end plug has a triangular shaped logo, might be an A plus other figures IDK. Pics are attached.

many thanks for all the help.

HNY and best regards

Hard to make out what's on the plug, the pics are a bit out of focus.

The radiator itself, according to your measurements, should be a standard type of large-tube radiator similar to the American Corto, National Aero and others. Ratings were standardized by then so any large-tube chart should apply.

Steamhead, hello, hope all is well with you and HNY. You have previously helped me with a few other issues in the past, and I Thank You very much. Rad dimensions are similar to Arco Corto. 8 x 26 for 5 tube falls in line with Arco Corto but mine are 25" high. Guess worse case is that I tool down the listed EDR by 5%, should be close enough for my Btu calcs. I will see if I can remove some paint off the plug for a better pic. Looked clear enough but have never seem that type of logo before as well as a tap point just above the plug. Most likely you have.

Again, thank you for all your help

best
