Well, that's a good question: what they go to.
I can't seem to find a model at all that has emblems that look like that.
http://www.motorera.com/honda/index.htmAll the 60s model Hondas used a black round badge kind of emblem with a wing and the word HONDA, sometimes with the cc's as well.
The CB/CL 350s and 450s all seem to have the wing and the word HONDA separate in the 60s and by the 70s, all they have is the single, simple word HONDA.
Very odd.....
*edit* the only thing I can find that's even close is what tech J said - mid 70s XLs and MTs used a decal that looked like that with white word HONDA, yellow/gold wing and black outline. But, clearly a decal.
I'm really curious now to ID what they go to...
*edit II* hmm.... curiouser and curiouser. I found a couple late 70s / early 80s models that look to use a metal plate like that - the 650, 750 and 900 C models and a Nighthawk or two... But, even then, in those versions, it looks like the wing "flares" upwards more as it extends back. In yours, the wing looks much 'flatter' as it extends back.
