Amaco 3C kick wheel (probable antique)

Hey, so I bought this old Amaco 3C kick wheel with an electric assist and I am having trouble finding information about it. This isn't the exact one I bought but I can't really gets pics of the one I just bought ($80 on FB Marketplace) right now because it's in the back of the truck. Does anybody know anything about them? This is pre-Brent era and I know Amaco made the first electric one in 1947. Picture #1- not exact wheel but same model. Picture #2- Plate on wheel I bought. Picture #3- wheel I bought in the back of a pickup truck and I can't get it out myself.
