Question - what is my bike frame?

[babubike]

I have had this bike for a few years and I now want to sell it, but because of the paint job I can no longer see what kind of frame it is and I really can't remember. Could anyone help? It has a cut-out rocket on it and I think its handmade. It cost a couple of hundred to buy second hand. Any help appreciated! Thank you.

Steel. It's more dirt jump than XC, and that front gusset is reminiscent of early On Ones.

don,t recognize your frame from the picture but that gusset looks quite distinctive , any other clues ie. is it steel ?, whats the frame no stamped under bottom bracket shell ? Is the steerer 1" & made for threaded forks ? any pics of that cut off rocket etc.

Thanks for the replies. I believe it is steel, the frame number looks to be B192, I think the steerer is 1'' but it might be threadless forks, not really sure though. This is the cut-out.
