Hi,

Here In an other g503.com thread "M416 Lunette and Casting for trade" I have noticed two things that I don't understand :
"M100 and the M416 use the exact same thick shaft Lunette", and
"The M100 Lunette is much more narrow than the M416 Lunette"

So are they the same or not ? , as for instance Midwest sell repro M100/M416 Lunette without any difference...

(I have this "incorrect" Lunette on the Bantam I just bought, that I would to swap to a correct wwii lunette, but I have to figure out what I have first..., picture unavailable yet but as far as I can remember the shaft is as big as the ring.

Thanks in advance,

Alex.

Early 1951 dated M-100's did have the WWII "thin neck" Lunettes from the factory (and no, it does not show in any of the SNL G-747 manuals) . The ORD 7328311 "thick neck" Lunette was installed on later M-100's and all M-416's.

Look for a number that is forged onto the shaft.

I believe that some of the first M100s used the THIN lunettes found on T3s and MBTs as Joel correctly stated!

Hello,

I have measured the shaft and the diameter is about 4,3 cm.
And yes indeed there is a very faint marking, something like AB6370 WO or AE6370 WD (?)...

Best regards,
