SOLD!Going thru recent SK boxes - found this. Appears it’s the K2RIW design, which used pair of 4CX250B’s,
parallel stripline. ( Original article in QST, Apr/May ’72.) However, many variations/articles out there on internet. (ARCOS made similar design in kit form)

Guessing’ this was to be 432 MHz -but- as no upper stripline found could be built for 432 / 222 / 144 - your choice.

A nice project using inexpensive tubes. What you see is what you’ll get. Additional pix on request.

Price: $25.00 plus ship. ( Box: 14 x10 x 8 @ 4 1/2 lbs. ) PayPal preferred, USPS MO accepted.
