WBCCI Number 2051 was first assigned in 1958
to a Richard and Phyllis Shaul of Pontiac, MI. They continue to be listed for #2051 through 1964
John and Dorothy McNeil finally show up in the 1962
WBCCI Membership Directory (membership as of 1961) as #5943 in the numerical listings only (no details in the aphlabetic listings). This is the first year that #5943 was assigned by the club. The McNeils are first listed in the alphabetic listings for #5943 in North Bend, OR in the 1964
Directory (membership as of 1963), but no caravans listed. Showing up in the numerical, but not alphabetic listings means they joined or renewed their membership very late in the year - too late to be listed in the alphabetic listings that were prepared first, but in time to make the numeric listings that were prepared last.
I did not have time to check further, but it is clear that #2051 was not the McNeil's WBCCI number, but they did in fact join the club.
