Mate in one with NO PIECES?

The following pictures depict chess positions one move before white checkmated black:

boards

The problem is, I seemed to have completely lost which pieces each letter/number represents. All I know is that the number substitution of the pieces is consistent across the board and that

1-7 include 2 pawns, 1 knight, 1 bishop, 1 rook, 1 queen, and 1 king

A-F include 1 pawn, 1 knight, 1 bishop, 1 rook, 1 queen, and 1 king.

Text boards:

---3-E--
-A--4---
---7----
------D-

-3------
574-----

---C-D--

So... what piece does each character represent?

Took inspiration from the snakes and ladders retrograde analysis puzzle and decided to make a non-retrograde analysis chess puzzle (which doesn't count in the fortnightly topic challenge :( )

The #3 looks like a

back rank mate, so 3 is the black king. C is missing from #2, so that can't be the king, which means that the white pieces in #3 are D=king and C=queen/rook. The only way the position is a mate in 1 is if 4 is a pawn and 7 is a rook.

The pieces in #1 and #2

can't be attacking the opposing king, so

- B can't be a queen or a rook (#1)

- E can't be a queen or a rook (#2)

- F can't be a knight (#1)

- 2 can't be a queen or a rook (#1)

- 4 can't be a bishop or a queen (#2)

- 6 can't be a bishop or a pawn (#1)

- 7 can't be a knight (#1)

Pawns can't be

on the 1st/8th rank, so A, B and 7 can't be pawns.

In #1 the mating move looks like

Qh6 by A=queen, protected by B=knight.

So the white pieces are

A queen, B knight, C rook, D king, with E and F being a bishop or a pawn.

Substituting the known pieces in #2,

Having F be a pawn would make it possible to mate with f8=Q, with all escape squares covered by white pieces.

Now we just give the black pieces some combination which makes the #2 position a checkmate after that move.

1 pawn, 2 bishop, 3 king, 4 pawn, 5 queen, 6 knight, 7 rook.

A queen, B knight, C rook, D king, E bishop, F pawn.

I spent the last two hours typing out in paragraph form all of this. You beat me to it though by 7 minutes. Nice work.

Good job! Some logic questions: On your first step, couldn't it be possible for 4 to be a knight? Also, on your second step, white could possibly be in check as long as they removed the threat on the mate, right?

@Jo. Hmm that's true, good points. I had thought about 4 being a knight, then disregarded it when I thought C was the white king, and forgot to add the possibility back. The second point hadn't occurred to me at all :P
