Rocky Mountain Cartridge up for sale

I just noticed today that case manufacturer Rocky Mountain Cartridge is up for sale. They are still operating, at a 4-month lead time, and the business is for sale concurrently. They make a wide array of obsolete caliber cases, particularly early American, all turned from brass stock on a lathe. They have headstamps, and most of them are uncataloged by collectors as far as I know.
