Woodward's A-26 was a Monarch 26, N137WG, which seems to have survived with several owners till 1981 - lastly at Anchorage, apparently abandoned after an accident following a flap rod failure taking off from Aniak.
Tennessee Gas had two B-26s, N171E, which ended up as an instructional airframe in 1965, and N5546N which went through various other owners before joining in the Confederate Air Force in 1967 - sadly lost in a fatal crash at Odessa in 1995. Apparently Aero Trader have the wreck in store.
