Clarence Peterson's patent for the Star Lubesizer was filed in 1934 and granted in November of 1935. The Lubesizers were manufactured by Star until 1993 when Magma Engineering acquired that portion of the Star business. Magma continues to make the "Star Magma" sizer to this day.
The Star Lubricator Sizer underwent very few changes over the course of its production, but one of the later changes was the addition of a Jam Nut at the base of the lube reservoir. Magma continues to use the jam nut.
Question: For those of you who might have purchased a Star Lubricator sizer directly from Star, when did you purchase it, and did it have a Jam Nut or not. I'm trying to pinpoint when that design change occurred.
I started this thread over on the Star Reloaders forum. Let's see if you guys can narrow it down a bit further. Based on responses on the Star Reloaders forum, the Jam nut was added sometime between 1956 and 1968.
