Single ring id

i have a question about this single ring. Can't tell what year it is. Thought a 1921 but maybe earlier

 

Hello, it looks like the first character in the serial number is a (B). That would place it around 1909 or 1910. The serial number is on the inner shaft.

 

I agree on the inner tube. It just looks like a P. Maybe it is faded as well. There are no other markings on it at all except the pat nov 15 04

 

"B"

 

You da man!

 

Thanks Toby!

 

It was common for the serial numbers struck on the inner tube to be only partially struck. There are many example s of this. Besides, a (P) would indicate a serial number that would have been put on a comb guard. The serial numbers were not put on the inner barrel any longer after 1913 or around then.

 

Here is the serial number range for single rings made in 1910. B222221-B697600. In 1909 serial numbers on some SR began appearing on the razor head instead of the barrel. However based on your razor it appears that this change over did not include all razors. A nice acquisition.

 

Nice single ring. Congrats. All teef straight and accounted for.

 

And where do you find this information?

Thank you both. I had seen these but never paid attention to anything under the letters since that was what I needed.

 

Various sites. Lots of good info on this matter and very well documented. Neat stuff. Several sites mentioned above. Here is a nice reference (some) consider as the bible. You can get as a download for $19.
