Stanley Vidmar keys are nearly impossible to duplicate. The beveled straight line
exterior edges are part of the key design. The key is manufactured and imported from
Switzerland. It’s router type exterior cannot be duplicated. All keys are stamped with
the appropriate combination number. The A designation is the series number followed
by a numerical A1 through A130. These keys are available and kept in stock for easy
replacement and additional keys if needed by the customer.
Might be wrong but its a good possibility!!!! And unfortunately there is no picture that i can find of the key's.......hope it helps somehow.
