Norm,
I would aggree with you that there is a slight variation in the size of the smaller 2.5 mm numbers. I measured mine with a digital metric vernier,
We thankfully still use both systems down here, imperial and metric and can be a pain in the toggle sometimes.
My 2.5mm numbers vary from 2.5mm to about 2.75mm and seem to correspond to the depth of the number in the wood which would figure.

They are nothing like the larger 4mm numbers however,

While on the subject of "pain in the toggle" I have recently had to sacrfice my dream of owning a nice 1902 Carbine as the money got spent on a new left hand toggle middle link. A new bionic titanium and teflon knee, only 3 weeks post opp and now walking around without crutches and climbing stairs, but, hell, I think I still would have prefered the carbine.
Regards
Murray.
