[Wild Skies]

In the Parker gun world I would describe:

Rare = about a handful, certainly no more than 10-15. You may search years or even decades to find one.

Scarce = a few more than rare, but less than 50. Seldom encountered, but examples do come to market from time to time.

I would describe runs of 50-250 to be uncommon, takes some searching, may not be available at the moment, but usually will become available before long.
