Pat, try HUT Products (
www.hutproducts.com), the same folks who bring us Crystal Coat and PPP Satin and High Gloss finishes.
They have "Metal and Domed Logo Kits" in finials, gold clips, and chrome clips (three types each) with a number of more general logos available (1-9 at $4.29 ea.). They also have "Foil Logo Kits" in finials, gold clips, and chrome clips (each in three types) with a selection of logos from cars, motorcycles, flags, and miscellaneous logos (1-9 at $3.99 ea). Prices are set by quantities ordered.
I haven't seen physical samples of any of these logo products. I was thinking of doing some MG logo pens for our local MG register (owner's club) and Hut has MG logos available in the foil kits.
Unfortunately, I don't see a Harley logo, but they do offer "Custom Domed and Metal Logos". Perhaps they would do Harley logos for you, however, you may need a release from H-D to use their logo. It is a trade mark. Call Hut at 800-547-5461 for specific information.
They have a paper catalog available on request. I haven't seen logos in any of the other catalogs I have. Hope this helps.
Cheers,
Stephen
