With regard to the cased 1845 proof set that was offered in Heritage's Newman One sale, the set was offered in its entirety by B.G. Johnson to J F Bell in October 1946 !! It was from the Col Green collection.

As you can see Bell returned it but was offered just the gold in 1947 and purchased it on 1/13/47. Newman ended up buying the rest of the set - offered in the Newman One sale.

Of course the gold ended up in Pittman's assembled proof set but it would be nice if all of these pieces could be reunited.
