[Rubbond]

Dear Cliff,
Surprised they made hoses like this in the 1950's (very common now).
The inserts are bonded to the rubber hoses during production using special
primers for the metal parts and chemical bonding agents applied before
curing the rubber to the metal in a steam autoclave.
If original replacement parts are not available, or something very similar
you could make to fit, you could re-use the brass inserts by simply
attaching new hoses with Jubilee clips. If curved hoses are required you can
use hoses of the correct diameter from any other car model, and even
lengthen them using metal tubing.
If you can get away with straight hoses, make sure these are reinforced EPDM
rubber hoses, i.e. intended for hot water, and not NBR (hydraulic) hose.
EPDM will last 5 times as long.
Rgds,
Andrew.
