My father-in-law dropped off a Pike Ejectoblade razor yesterday in absolutely fantastic condition. The disposable blade in it has a few light orange spots but otherwise, the whole shebang looks almost new. I really like the shape and feel of this razor and would like to compare it to my other disposable 'straight' to see if it's worth rotating into my group of users or if it will take a place on the shelf. I could probably clean and hone the existing blade but I'd really like to start with a fresh one. I found some replacement blades online that look like they would fit but I want to be sure before I buy them. Does anyone own one of these and know what sort of blades, if any, would work? This is the closest-looking thing I could find and NOS of the Pike blades does not appear to be available anywhere:

I apologize if this has been asked before, I ran a couple searches and didn't come up with anything.
