Blackmar-Diemer and other e|d2e-gambits

This thread is a part of my new program of classification of openings by their pawn stems. The notation e|d2e means that white has no pawns on e-vertical, black has no pawns on d-vertical but double pawns on e-vertical. Basically, it happens when black's d-pawn takes the white's e-pawn.

The prototype of this type of gambits is Blackmar-Diemer 1.d4 d5 2.e5 dxe4

Just looking at A00, I discovered 2 other gambits of the same type.

Barnes Opening: Gedult Gambit #1 (A00) 1.f3 d5 2.e4 g6 3.d4 dxe4 4.c3

Grob Opening: Zilbermints Gambit (A00) 1.g4 d5 2.e4 dxe4 3.Nc3

Please let me know about other gambits of the same type.

I found an other gambit of this type in A00.

Van Geet Opening: Berlin Gambit (A00) 1.Nc3 Nc6 2.d4 d5 3.e4 dxe4 4.d5

The Tennison Gambit: 1.Nf3 d5 2.e4 dxe4 3.Ng5 or 1.e4 d5 2.Nf3 dxe4 3.Ng5

Thanx Malcolm! It can be also obtained from 1.Nf3:

Zukertort Opening: Tennison Gambit (A06) 1.Nf3 d5 2.e4 dxe4 3.Ng5

Tennison --> Blackmar-Diemer --> Van Geet: Berlin gambits form a tower in HFZ metric. The height of Van Geet:Berlin above Blackmar-Diemer is 1 (e5 pawn instead of e4) and the height of Blackmar-Diemer above Tennison is 2 (e4 pawn instead of e2).
