Dr Scott's Safety Razor

I am looking for info on this razor I got from my local antique shop. Its a Dr scott's razor. Patents on the bottom are 4-19-87 and 5-19-96 . It has no blade stops, It uses wedge blades that are magnetized also they are shorter in length than kampfe brother wedge blades by 1 mm. It has a rolling guard and a 2 piece handle with a stropper that goes on the end. It has square Screws on the sides that adjust 2 sliding L arms that put tension on the top of the blade. There is hinged bar with a screw in the back of the razor that puts tension on the back of blade on a flat. Thanks 

They made 2 razors I saw
This one



And this one which actually describes a corrugated roller guard like yours.

Thanks Dave! Its a very interesting razor. The whole magnetism thing is funny, reminds me of the old westerns tv shows where a traveling "Dr" in wagon is selling a cure all out of a bottle.
