[Milsurplus] Fwd: TBX-2 question

[Hubert Miller]

The -4a has enough modifications that it's not just a modification of the -4.
I think it interesting that Nick's pages 4a has white face meters and mine has
black face meters. By looking at the pix on Nick's pages you can see the
transitions thru the different models.
