Gamefowl Rooster Comb Type

Comb: there is a lot we don't know about comb genetics, but here's what I do know.

There are 5 known locusts, containing 11 alleles, that we know of, and they control comb type:
1. Pea Comb Locus, P, p+
2. Rose Comb Locus, R r+
3. Duplex Comb Locus, Dv, Dc, d+
4. Breda Comb Locus, bd, Bd+
5. Smooth/Rugged Locus, hel, He+

Pea
1. P(Pea-comb) - autosomal, incomplete dominant.
2. p+(wild-type, pea-comb)- autosomal, recessive.

Rose
3. R(Rose-comb)- autosomal, dominant.
4. r+(wild-type, rose-comb)- autosomal, recessive.

Duplex
5. Dv(V-shape, Duplex comb)- autosomal, incomplete dominant.
6. Dc(Buttercup, Duplex comb)- autosomal, incomplete dominant.
7. d+ (wild-type, Duplex comb)- autosomal, recessive.

Breda
8. bd(Breda Combless)-autosomal, recessive.
9. Bd+(wild-type/Breda Combed)- autosomal, dominant.

Smooth/Rugged
10. hel(SMOOTH COMB)- autosomal, recessive.
11. He+(wild-type/RUGGED COMB)- Autosomal, dominant.

There are 10 comb types:

1. R/R or R/r+, P/P or P/p+(Walnut-comb)

2. R/R or R/r+, p+/p+(Rose-comb)

3. r+/r+, P/P or P/p+(Pea-comb)

4. r+/r+, p+/p+(single-comb)

5. r+/r+, p+/p+, Dv/Dv(V-comb)

6. r+/r+, p+/p+, Dc/Dc(buttercup-comb)

7. R/R or R/r+, p+/p+, hel/hel(Strawberry-Comb)?

8. R/R or R/r+, P/P or P/p+, hel/hel(Cushion-Comb)?

9. r+/r+, p+/p+(plus some mutation that causes the Crown to split at the very back)(Carnation-Comb)

10. Any combination of Pea Comb genes , any combination of Rose Comb genes , any combination of Duplex Comb genes , bd/bd(Breda-Comb/combless)

Any idea what comb Type my game rooster has? Thanks a lot! These are the best pictures I could get so far.
So, his crown doesn't match any recognized crown type. Which is very interesting, but considering we don't even know what exact genes are involved in recognized crown types it would be hard to determine what genes are involved in an abnormal comb. I think it's worth mentioning that gene mutations pop up all the time too, so your rooster could be the only chicken with a crown like his, because it's brought on by a new gene mutation. But, it's also possible that it's just a deformed crown. If it's controlled by genes it should be able to be passed on to his offspring, if it was caused by environmental factors, like humidity during gestation or something like that, then it's unlikely that his offspring would have a similar looking crown.
If you wanted you could try to breed a new crown type.
