[TR] TR3 heater motor

[Angelo Graham]

Hello List:
Was working on my heater and turns out that the core is still good 
after sitting for 40+ years. Just wondering if anyone has found a 
modern substitute for the Smith's fan in the unit. Mine works, but it 
is pretty feeble even with direct 12 volts applied. Intend to clean 
and re-lube the motor. Has anyone tried to fit a fan motor of similar 
size - VW, Toyota, etc that might work? Would be nice to have a bit 
more air "rushing" through the defroster hoses.
Thanks for any insights.
