Sorry, the only info I have on the clogs is that I downloaded them in the year 2000

and they were made by someone named (not a joke) byteme0k. His file says he wasn't the one who actually made them, but he only adapted them for
Poser from some DXF files (

does anybody still even use those?), so they shouldn't be further redistributed (why bytme0k ignored his own advice, who knows).
