Say hello to my newest razor collection family member... 1960 (F-4 date code) Allegedly a prototype but I'm not so sure I agree with that since the regular common Fat Boy was out in the same year as was the gold "Fat Boy" known as the Executive. Just doesn't seem plausible that with all 3 of them out in the same year, that the 195 made in the last 3 months of the year was a "prototype" in a retail case. To me, prototype means not available to the public. Why would Gillette make retail cases for the 195 if they weren't available to the public? Achim has a gold "Fat Boy", aka Executive, made in the first quarter of 1960, 6 to 9 months before this fourth quarter 195. Prototype or not, this razor is super rare... the original case for it - with the magnifier in the lid on the right side of the lid - is even rarer. I got both. The case is a little worse for wear (a crack in the lid, a hinge broken) but even having a bottom dial case is a feat in itself.
