Welcome to SRP. Sounds like a Shapleigh Hardware Diamond Edge. They were a distributor of knives, straight razors and cutlery in general and here compliments of google is a bit of history on them. Probably Solingen made AFAIK. With cracked scales and a 1/8 chip you didn't get a bargain. Read the SRP Wiki linked in the posts above for more info on getting into shaving with a straight razor.
