My parents and I were living in Peru in the late 50's, early 60's when I was a little kid and I've always loved this opener. Dimensions are length = 4/58"; width at base = 1 1/4" http://www.flickr.com/photos/32983226@N02/3079476008/" onclick="window.open(this.href);return false; ...

Can't really help you with the plate, but I have a bottle opener from the same silversmith. My parents and I lived in Peru when I was a little kid, so we got it in the late fifties, early sixties (1960's, that is).

I'll post a picture of it.

I haven't been able to find anything on Kohler.
