Kohler large tube radiators

ChrisJ Member Posts: 15,452
I have a single pipe steam system, but felt being these radiators could also be used for hot water I would post here.  I noticed all of the sections of these Kohler radiators appear to have a number which looks like either 6   24 or  8   24 near the bottom. 

What are the chances this is a manufacturing date?  My guess was the central heat was installed in this house sometime in the 20s so that fits but for all I know this has nothing to do with it.

All opinions welcome!
