Why are these original A-2s not bidding higher?

[GoodTimesGone]

Here's two original A-2s I've been watching. I'm amazed they haven't gone higher this late in the auction. Is there something I'm missing? :? Perhaps it's because the sellers ship in the U.S. only. (Or because the serious bidders are clever enough to snipe in the last seconds.)

I think you have already answered your question.

You've also answered a question. I was wondering if they were authentic. (Thought so but wondered about the details.)
Thanks Andrew.

Yes they are originals from 1942 contracts-Dubow and Aero.
