[AMSAT-BB] Help identifying mystery antennas

I was asked to help ID two possible satellite antennas by a fellow club member; he was storing them for another ham (now SK). The antennas have no identifying manufacturer labels or model numbers. (The bar code visible on the 2M antenna is from the U-bolt plate.)

Appears to be a 5 el 2M and a 10 el 70cm, circular polarized, the elements are mounted above a square boom. DE looks like an insulated from boom split element fed through a balun and semi-rigid feedline. I'm guessing some long-gone manufacturer, or an import or a well-constructed homebrew from a published design, and not M2, HyGain, or Cushcraft.
