The Enders Speed razor was developed around 1930. It was sold by the Enders Razor Company. One of main selling points they tried to get across was the fact that this was a “one piece razor”. You didn't have to (and couldn't) take the razor apart to change blades. The blade slid out and clicked in place. Thanks to an adapter sold by Pete Hendrix some years ago these razors are now usable with the Schick B-20 Proline blade. The colored Speed Shaver handles made their appearance in the late 40’s or early 50’s. I became interested after a former member who’s passed shared pictures of his razors. They are great shavers.
Here you go, Scott, I bought it about three years ago from Hendrix Classics. He could probably let you know from whom he sourced it.
