Here is another adjustable I used to own that I found one of my pics I took of it for elsewhere. This is a Cooper DE adjustable. It was sold under other brand names but is unique in that it uses a steel washer to adjust the gap.depending how much you tighten up the handle.

Another that is technically not an adjustable but the way the locking mechanism for the cap works allows for different blade gaps depending how far you tighten down the cap. This razor is a Cooper Monobilt.

Although Cooper made razors with that handle, I'm pretty certain the adjustable is the Berkeley Shave Selector which has the same plate as their previous Custom Shaver. I have the same model as yours with no maker marks but also had one that was marked Berkeley Shave Selector. Not seen any others with the extra plate

Handle was used on Berkley and other brands, it was also used on the non adjustable Cooper Kant Rust razors. The adjustable pictured there was also sold under other brand names like Berkely. The actual handle and razor heads were cast by a smelter named Doehler Jarvis, they also produced a version under their company name.

Here is proof that particular razor I posted is indeed a Cooper branded adjustable and not a Berkley.

Was just going to edit my post as I saw the ad in searching. My current model must be the Copper Kant Rust and Here's my old model I sold. The Berkeley Custom Shaver has the same adjuster plate and predates these by 10 years.

Far as I know that style handle shows up after WWII and that particular adjustable unless Berkely version was sold earlier was first introduced in 1946.

What is also interesting about this razor regardless of the brand is it is far as I know the first DE razor to be sold as an adjustable. Anything prior even if you could adjust the blade gap by not tightening the handle all the way was not advertised as such.

Not the handle. The Berkeley Custom Shaver with bakelite handle had the shim and predated these (1937) making me think they were the originator of the adjustable knob. I could be wrong.

I've never seen on of those before and yes since it was indeed sold in 1937 that makes it far as I know the first DE razor with an adjustable knob.

Technically the first DE adjustable circa around 1910 for Gillette.
