Ebonite UStrike Tenpin Bowling Pin

Here is an Ebonite tenpin bowling pin. It is the UStrike brand and is rather uncommon. In fact, I was unable to find any contemporary models in the U.S. and this one had to be obtained at some expense from the United Kingdom. I have heard that Ebonite is a rebranded form of the uncommon Diamond Duramid pin. This from posters on bowling technical forums. As pins go, it's unremarkable in all aspects. Cosmetically plain with nothing particularly notable in either design or decoration. Standard size and control weight.
