x1111499 dist.

[hiperf69]

Hi Guy's, I picked up some great parts at Jefferson Wi. Swap meet but one thing was this 1111499 dist. With an "x" stamped in front of the number.
Just wondering what your thoughts are on these.
I know these are real and have had others like this, just looking for help and info.
