What is real interesting is that I bought a line lock that was in a box (more of a black and yellow Hurst from the 1970s that looked just like the one you have on the right. The switch had a black button on it like that one appears and the solenoid did NOT say Hurst on it anywhere. It almost looked like an off brand re-packaged. I ended up returning it to the guy in the Auction because nothing said hurst on it, and I paid "Hurst money" for the thing on ebay.

I highly doubt that somone would have done that twice, but yours does look that way a bit.
