I think it is a 47' because of the "collar" near the top of the handle. I only know 47's that have that. Not all 47's are like that.
Interesting. I wonder why that is? But remember, I let you have that one since I got the lot with the bulldog.
Thanks! It is caseless, but it was quite a find for me. I wish these razors would have offspring! I could just put two in a box and wait a bit to grow the collection!
