Replacement security tab for a desk drawer

Hello,

I have an old roll-up desk with a plastic security tab found in the back of the center drawer. The tab was manufactured by Ronthor in NYC and the serial number is R-51-424.

It wears and tears quick, so I'd like to get some spares. Do you have anything similar in your inventory? If not is it something you could manufacture?
i would happily pay for a large quantity to justify the effort.

Thanks,
Lee
