"... an old type of handle bar designed for track bikes and path racers which seems like a cross between moustache and drops. Perhaps you have seen these a vintage photo."

I'd like to see a pic too. There is a guy I see in my neighborhood w/ a pursuit bike that I think has bars like what you are talking about. I really like them but don't know what they are called. the ones I've seen are basically like drops only they don't drop down nearly as much and have basically little to no reach.

Kinda imagine if you had bullhorns with a deep drop (for bullhorns) and turned them around so the horns were facing you and make that have sex with normal drops and their baby is what I am talking about. Maybe your description of mustache bars crossed with drops is better...anyway, I think you know what I mean. What are those called? who sells them? etc. etc.
