Where can you see PS Stix seriál number info?
Can find dims in a board
The professor said he keeps all the records, so he can look them up as needed, but there are no online or other resources where people can go find something like that for themselves.
As to the numbers themselves, on any of his boards there is a line that has this - PS SN XXXX (the specific run of boards) and then - XXX (the specific board in that run)
Eg PS SN 038342 - 0012 which would be the 12th board in the specific run, that run being 38342
I don't know how willing he ever would be to look up any info, but you might find you get a reply with at least some info, if you were chasing a specific shape or something similar.
Hope that helps.
