Brand and Value of Vintage Push Mower?

I have my dad's old manual push reel mower. I can't find the brand on it, but I did find "STK No 8D23 CDE No 85" stamped on the top of bottom plate. It has made in the USA and the color was/is green.

It is from at least the fifties, maybe earlier. It has a wooden handle with a metal shaft that at one time had a label on it. Looking for a possible brand and approx. value.

Thanks.
