I believe the #77 may be the only two piece Gillette made with a retainer ring to allow the cap to be removed without allowing the knob to come out. If there are others I's be interested to know which models. I see it as a design plus as the less pieces rolling around on a wet sink the better for me.
and the 2-piece Gillette NEW Belmont DeLuxe , white plastic Tech
The Gillette New Traveler #4 set, #77, #88, and the Brit Bakelite Set all have two piece razors.
Two piece News are great shavers.
The thin handle and relative light weight aren't the best features for me.
The British made open combs are all very well made and right in the sweet spot between efficiency and comfort.
After getting my hands on a #77 or #88, same razor depending on the package they came in, I searched out and found a three piece British New with a flat bottomed plate for use on beefier handles.
Now that's just something I didn't need to see pal.
How's a guy supposed to save up for the Holidays if he keeps seeing razors he can't live without?
