Caithness Glass hollow fishing float with engraved with a single seagull and seashell top produced by Caithness Glass in the 1970's-80's. Perhaps a very limited edition Caithness Glass item, I have not found any images of a fishing float on Caithness website or by searching online. With a Caithness box. Size is approx. 10 inches or 25.5 cm. in circumference. Weighs 12.8 ounces or 365 grams. Not signed or marked. It is in excellent used condition. It is a beautiful work of art glass with soft blue waves around the base raising to the middle of the float.
