Comb Type?

[frizzlefritz]

Hello!
I have this young cockerel that we bred from a RIR roo and a barred heritage breed hen (not exactly sure what breed she is, but she has a pea comb). He has a very interesting comb type and I’m wondering if anybody knows what it is. Kinda looks like an enlarged pea comb, but has what looks like a hollow tube in it. Any thoughts?

Probably a mix comb??? Could you get a close-up? He is very handsome!

It looks like it could be a rose comb but I'm not sure. Could you get a bigger picture?

You would call it a modified pea comb.
