Straight Razor Used in Film 1929

[Mycall]

hi
Hope someone can help

I'm trying to ID a razor used in a 1929 french silent movie entitled "Un Chien Andalou". At first I thought it might be relatively easy, but having scrolled through 100's of pictures on all sorts of web sites I can even find one that is even close. So hopefully someone can help. I have attached a picture with the clearest frame grabs I can find. The spine has notches and on the blade, there are 2 words encased in a sword motif with a heraldic shield with what looks like a crown ??. I have done a drawing and I'm sure the second word is 'BEST'. The first Word looks like it has 5 letters and ends in ___NO. ???. Everything looked so easy when I started with all the clues......

Thanking you in advance

Michael
