Gillette 3-piece open comb: ID please

[zero]

Was just wondering which Gillette model this 3-piece open comb Gillette razor is?

Thanks very much!

It looks like a Old Type single ring from 1906-1920. Is there a SN inside the head?

The "/" would actually be some number. But, based upon the "E" prefix and the leading "7" number, it would be a 1918.
