Identifying Radiators

My company is in the process of renovating an old school into apartment buildings. The school was built in early 1900's and is heated with a steam boiler/radiators. We know the boiler was replaced in 1980 (Kewanee M-Type), but we have no documentation on the radiators. There was major work/additions done in 1908 and 1934 and we assume they come from those time period. Is there a way to tell? Would they have any kind of markings?
I've attached some pictures of different types in each "wing" (1908 and 1934).

By the time these were installed, ratings were pretty much standardized between the different brands. So you could use the charts for pretty much any brand.
Dan's book "E.D.R." contains a lot of different radiator rating charts. Go here to get it:
