old myson round top radiator output

[Stevenhouse]

Hello, does anyone have any details of the heat output for old myson round top radiators? The radiators do not have fins and date from 1970s / 1980s. There was another tread where there seemed to be attachments with the info but the links have expired. Thanks for any help.

The above is probably accurate enough for most practical purposes.
