The clip has the word "Neldun," as well as "Reg'd" and "Pat. Pend'g." Underneath the cap is a simple lighter.
Note that the "N" in Neldon has a tail that extends across the rest of the word, just like early Ronsons (including the Lite-O-rite). Note also how the lower half is identical to that of the Lite-O-Rite by Ronson. Although I have nothing by way of hard evidence, what I do have suggests there is a connection.
