You might also consider vintage razors, a lot of them are brass and they've stood the test of time to get this far.
Alternatively, if what you really want is machined stainless you can probably get it for that price from dscosmetic or yaqi on AliExpress. They have many models so it'd be worth searching out some reviews.
This seems like a really nice size, good compromise between heft/lather handling and agility. Plus I like the jimping on it. Somehow I suspect you'll hang on to this one.
And ya, wow, did you stumble onto a hidden cache of underappreciated and underpriced blades or did you set out to expand your collection like this?
