N.n. Hill Brass Co. Rare Antique Bicycle

This listing is for a N.N. Hill Brass Co. RARE Antique Bicycle Bell unique mould piece display. It is an excellent Early American Accessory, made in Connecticut USA circa 1887. It is on a folk art style plaque, which is inscribed, “N. N. Hill Brass Co Bycicle Mold East Hampton Conn. Cir. 1887”. I have not seen another quite like it. It is an excellent item for collectors of bicycle memorabilia / antiques, gifting, display/ decor, gifting, and much more! Perhaps they could be turned into some musical machine or sculpture as well that can actually play notes- the possibilities are endless!
It is in great antique condition. It could be re-mounted on a more professional looking plaque, but the original has a certain charm to it. I am unsure exactly what the inscription means by mould piece, whether this is a test cast, a mould piece, or a complete set “fresh off the line” never taken apart and assembled. If that is the case- In a sense they are New old stock. I believe they are in fact a mould component due to the thickness of the center shaft connecting them, its a large amount of brass to waste every time you cast. They have a pleasing patina, I have not cleaned them at all to not disturb it. Cleaning is at buyers discretion.
