Hello Allan,
I found a comic strip that was not listed in your book.
It is "Horace and Buggy" by Don Edwing and Paul Coker Jr., syndicated by McNaught Syndicate.
From browsing Newspaper Archive, I found that it ran in the following papers between February and June 1971: Snyder Daily News, Scottsdale Progress and the Kannapolis Daily Independent.
I was able to get an example from the latter, dated April 11th, 1971 (but with comics from the previous day):
