Trivia question about Ansen Sprint wheels

When did the first offering of the Ansen "Sprint" style wheels occur? I know they were marketed as a cheaper alternative to the big names like Halibrand and even got some of the halibrand style worked in but who knows the answer to this question? What type cap did these earliest version use? TIA!

 

The most popular Ansen wheel was the Ansen Sprint, which was introduced in 1963.

The Sprint was the first "aluminum slot" wheel, being centrifugally cast, a technique seldom used in the wheel industry back then. They were produced on a tracer lathe and shipped in their natural, machined finish.

Ansen Sprints featured five slots in the side of the wheel. This design was later copied by many wheel companies, including American Racing Equipment, Cragar, Fenton, Mickey Thompson, Superior, and US Indy.

All Ansen wheels were made of aluminum and had their name cast into them.

Ansen produced some five-spoked wheels were unique in having no provision for the standard five-screw, bullet-shaped center caps that were originated by American Racing Equipment. Instead, Ansen used their own smaller, round center caps (along the lines of the caps used on the American Racing 200-S "daisy" wheels). Another Ansen five-spoked wheel used a center cap that interchanged with American Racing caps. Ansen five-spokes were only produced with rounded, as opposed to peaked or creased, spokes.
