Jessops Steel Razor?

Hello,

This was one of the first razors in my stable. I found it on ebay and I am not able to find any information about it besides the connection between Sheffield and Jessops steel. Perhaps someone here could tell me more about it?

It is my most lightweight 5/8-'' razor. I do not know if it qualifies to be a singing razor but it is very hollow ground, "sings" on a hone and tells me stories about every single hair when shaving. It is an excellent shaver and it can give me BBS with a very light pressure. It is more prone to overhoning than my other razors. The scales are pale yellow/beige plastic with faint stripes.

Does it have any brothers around?
