Hello.
I’ll double-check tomorrow, but as far as I recall, they don’t have identification plates; however, I am certain they are genuine Scheel products from before the company changed its name following an acquisition or merger.
I’ve handled quite a few of these original Scheel 300/400/500 seats, and I tended to see identification plates more often on the ones made after the company name had changed.
I’ll let you know tomorrow.
Have a pleasant afternoon.
Best regards.
Lucas.
