"Wally Brown" -- any evidence it really aired?

There is a TV series listed in the database titled "Wally Brown" (1979). However, it has no distributor, no release date, and no episodes listed. Nor have I been able to find evidence that it really aired. In particular, it is not listed in The Complete Directory to Prime Time Network and Cable TV Shows, 1946-Present by Tim Brooks and Earle Marsh.

I looked it up because I saw a game show on which Ron Masak appeared, in which he said he was going to be on a series titled "Wally Brown" which would air in October (of 1979) on NBC. So this must have been a real project, but it didn't necessarily make it to broadcast.

On the other hand, there is also a TV movie in the database titled The Further Adventures of Wally Brown (1980) (TV), with most of the same cast members. This really did air, as a pilot, on August 21, 1980, on NBC. And it's listed in such books as Encyclopedia of Television Pilots; Encyclopedia of Television Series, Pilots and Specials; and Unsold Television Pilots: 1955-1989. It seems unlikely that NBC would air the 

Before anyone says, "Doesn't the title 'further adventures' imply that there were previous adventures?", I'll admit that it normally would imply that, but the title could have been chosen for amusement rather than being meant literally. The Beatles had a song called "The Continuing Story of Bungalow Bill", yet Bungalow Bill had never appeared in any of their songs before and never appeared again, and there was a movie called Leonard Part 6 without any of the first 5 parts ever being made.

So my questions are:

1. Is "Wally Brown" verifiable as being a TV series, or did it never make it to air as a series?
2. If it never aired as a series, should we merge the series into the pilot The Further Adventures of Wally Brown?
