Possibly, but I am familiar with the cracks being caused by press fitted plugs into nonadjustable Gillettes, where any stress from tightening doesn't transfer to the barrel. Also, foreign clone coppies of Gillettes, don't seem to duplicate this problem, even though it is very common in genuine Gillettes.
i scored an NOS 1920's old type with case,shipping box,ther works,and the handle was split end to end.
And now, to make it on topic, I go back to the Gillette double ring. And to make it scientific, I offer a theory and its prediction. If the double ring plug, barrel, mismatch is the problem, then I would expect small cracks at that end of handle in most Gillette double rings. Here's mine:
i have seen many new improved ie bostonian type razors and new deluxe criterion with similar splits at the head end of the razor.most likely from pressed in plug also..evidence of overtightening without a blade present on the knob end also..
Just a little common sense here. If it were just the plugs doing the splitting, then we wouldn't see the flaring of the ends. The flaring is caused by over tightening, If it were just the plugs you wouldn't see the cracking continuing down the barrel. If it were just the plugs, you would see cracking in NOS sets, also in other sets that are prone to splitting. Just a poor design, with the handle prone to slipping farther onto the plug, hitting the end, causing it to split. Perhaps if the manufacturer had epoxied, or soldered the end pieces to the handle, there wouldn't be any splitting.
The splitting was caused by a mismatch between the 'plug' OD being slightly larger than the 'tube' ID. Pair that with a harder, brittle brass alloy, and you have a recipe for split tubes. One of the rare instances where Gillette flubbed a razor design. My guess is it took a decade or more for the problem to reveal itself, which is why we see the occasional NOS razor with cracks and splits.
i had purchased one some time back,1920s 3 piece old type,gold pocket set,handle split end to end,ebay has long since ditched the pics.i parted it out and reused the case for something else..
There's some threads with them on B&B. I'd have to look them up. Edit: But yeah, split. Razor still sealed in the original cellophane.
The lack of cracks on this unmarked French double ring, help to distinguish it from genuine Gillette. https://theshaveden.com/forums/attachments/dscn1639b-jpg.292666/
Didn't know the French also made a knockoff. I would think the the number of teeth would be a bigger clue than the lack of cracks. (also works on German copies). Leresche, I'm assuming? Nice razor.
Thank you. The number of teeth definitively makes it not Gillette. Also, the fact that the double rings look like they were cut into the top plug on a lathe while the Gillette original looks like the double ring part was formed by rollers at the lathe. I remember Leresche being my best guess, but it was so long ago I can't explain my train of thought. The box shows a strong Gillette double ring influence, but all of the writing has worn to illegibility.
There's also another other one, but it's rather much nicer and comes with instructions. I'll be watching, and not bidding.
The other one is NOS. It should go for a stupid high price. Don't worry, I will pass on that one too. Happy bidding.
