Hook - 10 - 14
Tag – Red Floss
Tail – Golden Pheasant crest
Body – Golden Olive Dubbing

Body Hackle – Palmered golden olive and claret hackle
Wing – Bronze Mallard
1st Head Hackle – Game read hackle
2nd Head Hackle – Blue Guinea Foul

Really it's just a golden olive bumble variant. I think the johnson bumble is pretty much another variant, I will keep looking though.
