1923 finds listings at the same address ⁵ and we confirm that DeLancey's first name is William J ⁶. There is also another listing in 1923 that lists 3 prinicipals of the company but not which postions they held, Clyde P Delancey, Raymond W Farnum and Wiliam J Farnum. ⁷. There is also a referance to a large ad on page 783 which is the same page as the last reference so I assume it was the same.

In 1924 we see a company listing at 10 Meeting Street ⁸, Pawtucket and another listing for Raymond W Farnum being associated with the company ⁹. Then there is a 1924 large ad that shows the company address as 10-12-14 Meeting Street in Pawtucket ¹⁰. The final listing found in 1924 is one than again lists Clyde P DeLancey and Raymond W Farnum and listed as selling wholesale radio merchandise. ¹¹.
