The plastic Duncan Butterfly had not changed much in more than 40 years that it was in production. It had a plastic body and a fixed, steel axle. However, in 2012 Duncan released the Butterfly XT that sported a ball bearing axle.
The model in this exhibit, with its "lace wing" butterfly profile image on the side, is from around 1979-1980. It is rather unique because the front of the packaging says "Butterfly Yo-Yo With New Reslon Coated Axle". The special axle indicated Duncan's effort to improve yo-yo spin times, long before mass produced ball bearing yo-yo axles came to the market. (The innovation of mass produced ball bearing yo-yos is credited to Tom Kuhn for his disruptive Silver Bullet 2 or SB-2 that was introduced in 1990.)
The metal axle is Reslon-coated. Some people refer to the coating as Teflon, but that is incorrect. Reslon was Duncan's proprietary thermal bonded fluorocarbon resin coating (read: plastic) that reduced friction between the axle and string, and allowed up to 20% longer spin times. Reslon axles were also used on Duncan Imperials and Duncan Professional style models (such as the Duncan Super Hero yo-yo series) in the early 1980s. The Reslon trademark, owned by Flambeau, was officially registered August 28, 1979. On December 15, 2000 the trademark was cancelled.
See the Duncan 1979 product catalog that introduced Reslon axle yo-yos for the first time!
