Hi John,
Except that the block is full of scale buildup unless it has been
recently chemically cleaned, & the insides of the radiator tubes have
buildup. Also, solder bloom over the years can partially plug the tubes
& the bonds between the tubes & fins can partially separate.
No 40 year old radiator is up to spec. The design was marginal in the
first place. I once had a three year old BN2 that had similar problems,
though not so severe.
