Razor identification please!

Hello everybody,
I bought this razor online (Tilly) a couple days ago. The description said "Hefty". I don't think this is a brand name, rather an attribute, I guess. The only thing written on the blade is shown in the second photo. The scales are Desert Ironwood by Bill Ellis. This of course doesn't mean Bill ever saw this razor. He could have just sold the scales to someone. The blade is a wedge 6/8". My question: Does this blade look familiar to anyone? Is it maybe a custom job? It is an excellent shaver!
