I cant post pics until Sunday afternoon.
The razor in question looks almost exactly like a 40s SuperSpeed.
The date code is Y4.
from research i've done looking at date codes i'm assuming this is a 1953 SS. I thought they only made flare tip SS in the 50s.
or it could be a 1978, but i dont think they made razors that look like 40s SS in 1978, did they?
