This is a good example of an early Long Comb "New" style Gillette safety razor. This one is marked "Made in Canada". In the US, the reissue patent of 17567 was granted on January 14, 1930, so that's about as close as we can date it. I'm not familiar with the Canadian patents that are marked on the handle.
This type of razor is preferred by many over the Old Type, or the Short Comb New. The longer tines in the comb, and the way they turn down provide a balance between a close, aggressive razor, and smooth control. This example has a ball-end "new" handle.
In spite of its age, it will use standard double edge razor blades. As you can see in the photos, the razor is in quite good condition overall. There has been some loss to the gloss coat over the gold plating, but it looks good in your hand, and it's still smooth to shave with. As with most Gillette handles of this age and type, there are some cracks. There is one on the head end of the handle and another on the ball end. We tried to get photos of both cracks, but the one under the head doesn't show up much in the picture. Neither is very large. They are on opposite sides of the shaft, and the parts are all still snug.
A comparison photo showing the long comb vs. short comb head is provided. Only, the long comb head (with a ball-end handle) is included.
This variation on the New is a somewhat rare razor to collect. The long comb head makes it interesting to use. Nice piece of shaving history.
