Hey there Weagle;

That's interesting. I just calipered all mine and the measurement on the right is 2.83 mm and on the left it's 2.9 Not very much at all.

I wonder why this is so.

The thru hole in the back is slightly off center to the loading gate side.

I had always assumed that the thru hole was centered on these hammers, however after looking at a few hammers of different vintages I discovered that the hole is slightly offset. Just noticed this by accident and thought I would share the observation.
