Inspired by this thread, I went by my local Outdoor dealer/hardware store which has a big Ilco stock and got two cut for $5.30 total including the blanks.
I first went by the local Kawa dealer whose parts counter kid (he looked about 17) honestly said, ''What kind of bike is that?"
Then he said, "We don't have those, but we can order them. They're $22/ea and we have a HAND cutter <WTH?>"...
To his credit, thenhe quietly said, "Go to Howard Brothers, they have a lot of Illco stuff. They might have that..." <Much appreciated, btw.>
$44 vs $5? Really? It's a KEY blank... I was prepared to pay $10 just to be supportive, but not $44.
