My TR3B had an overflow bottle when I got it in 1981, and I kept it after
restoration.  Same basic location as Randall's.

Here's "before", looking from the air filters toward the front.  Note the
open space alongside the inner wing and the radiator.

And "after".  Some of my original bits, and some new ones from TRF.
