"Pennsy" razor - anyone hear of it?

I haven't been around for a while, and haven't been adding razors to the arsenal, but I was at an antique market the other day, and couldn't resist picking up a vintage straight razor that was marked "Pennsy" (with the quotes) on one side, and "Made in Germany" on the other. I wanted to get an idea of how old it was and whether they're well regarded or not, but both Google and the forum search function turned up nothing.

Has anyone heard of this razor? Any info would be appreciated.

As an aside, it sharpened up really nice just going through the grits on the stones and good stropping - about 15 minutes work altogether, and gives a good shave - I got it over the weekend, and have shaved with it twice so far. Nothing fancy, but I'm not complaining for $15.

Thanks!

Just a guess but maybe railroad related. They refer to the Pennsylvania Railroad as the pennsy Line.
