There are no markings on any of the 4 sides. I think the identifying markings may have been covered when it was last abated. If it helps at all, the locks on the cabinet doors are all interchangable "American Lock" brand.

This issue is still unresolved

Emailed to PSE to check if it belongs to them.

Thank you

PSE states graffiti removed.

Thanks for fixing this issue!
