2 duble ducks, a puma and an otto

I got a pretty good deal this week on these 4 very nice shave ready razors.  The puma shaved like a dream and took off 3 weeks worth of growth in a single pass. I cant cant find much info on the Puma or the Otto, I was wondering if anyone had good information on either of them.

I know nothing of straight razors, but you’ll get some excellent info shortly. They’re good looking tools. Congratulations on your good fortune!

Btw, when I saw the title of your thread I thought you had a joke coming
