I have 5 of these available at $1.99 for 1, shipped to a US address. PayPal is fine and additionals keys are $1.50 each.
These keys are new and unused. Let me know here, or via email.
These have been added to ChipGuide. Note also that they do not include the now customary Orleans numbering, nor makers mark ("www.plicards.com").
Thanks for looking!
