TBI questions

[Fran and Bud]

I have one BBC TBI (2") that I believe is pretty early - had the hot water
heated adapter that opened out to match Q-jet manifold.  The injectors in it
are Maroon (Dark Red?) - Lt.(Baby) Blue.

Your parts guy may be able to tell what its original application was from
the Production Number on the throttle body casting - PN17087021.  I have
never attempted to find out what it was from.
