"The First SE that was designed for the Current Gem blade was the Gem Open Comb Micromatic or OCMM on 1929/1930... The OCMM, Gem Clog Pruf, Bullet Tip, Gem G bar, Gem Featherweight/Ever-Ready Natural Angle, Gem Push Button & Gem Contour were all Designed to take the Current Gem Blade..All the SE s before the OCMM were designed for Stropping Blades."
I think they'll work with everything after, and including, a 1912 on the GEM/Star/E-R side. Not sure about the lather catchers 'cos they were designed for wedges, so surely the shim will unseat the correct bevel angle..?
@Fergiebilly says the later Gem + etc models (after the 1924) were designed to work with the current Gem/Personna blade, but were they maybe were designed to work with
both the current
and the old "corrux" blades..? I got two old, wrapped Ever Ready blades - 1950s? - in the post yesterday (gonna get some Cru steel blades - WW1 & WW2 era - from the same vendor soon). They are
really bloody heavy, with an even heavier (thicker?) spine than the old 100 year old "GB Star" blades. They both had some rust, not on the bevel surface itself though, so I cleaned them up with razor blade, WD40 and elbow grease, keeping away from the blade edge. They're sitting in WD40 now. They were pretty sharp, grab a wet thumb nail, cut a stretched hair, but will need extra stropping because WD40 is an abrasive (which is a bummer as I dinnae have any strops, CrOx or balsa !)
