It was certainly cheap, and I'm not unduely concerned that it's not
giving me 0.1 mm accuracy, but I couldn't believe, 'til now, that anyone
could manufacture something purporting to be a vernier scale when it
isn't one.

I suppose there are different consumer laws in China :)

It's a direct copy of a circa 1950 Japanese non vernier caliper
(export model).

Easy, metric at the bottom and Imperial at the top markings
not really that accurate
if you want a vernier scale then buy a digital one
the one you show costs about $1.50 to buy
and a digital one you can buy for just under $10
