Compulsive offer Id.

So I lowballed an offer on a $250 razor on ebay. To my surprise the seller agreed to the offer which was lower than 50% his selling price. So now I'm expecting an 8/8 round point razor. I would like to find a bit more about the brand. I did a quick search here, and i only got a picture of some 14 gens, but no infoon the brand, dates, or history.
her is the link to the razor (it looks near mint):

It looks pretty clean. I had one of their 14's before. It was a solid razor, but not entirely my cup of tea. I did not look up any history on it, but I am curious. They are not in Goins or the few other places I have checked.
