This listing is for one key as seen in the photo (buyer gets one key even though the photo shows how both sides look).
This is a vintage key, not a recent re-cut.

In 1947 or 1948 Seeburg began using their S series of Illinois locks for all of their wall boxes.

There are 1001 keys in the series (S 000 through S 1000).
All the key numbers I have at this time are listed in my store - if you do not see a particular number than I do not have it, so please do not message me to ask for any numbers not listed.
Thank you.
