| "DORENA" Timberlog Lane. VANGE. 1st Feb, 1933. To:- Mr. J.W. Eldridge. Dear Sir, I thought it would interest you to know that I have been using 4 of your 'NER - MIS' adaptors on my sparking plugs fitted in my Chevrolet engine for some weeks. Previous to using them I had a lot of trouble with oily plugs, but since they have been fitted I have had no trouble. Have also used them on plugs with cracked insulators with satisfactory results and can recommend their use in every way. Yours faithfully, Signed. F.G. LETTING. | ||
