Question

Between 1963 and 1965, how many skateboards were estimated to have been produced

Answer 1

I'm sorry, but I couldn't find any specific data or estimates regarding the number of skateboards produced between 1963 and 1965. The skateboard industry wasn't as developed during that period, and it wasn't until the late 1960s and early 1970s that skateboarding gained significant popularity and production numbers became more documented.
