[DeTomaso] Brake problem

[Larry - Ohio Time Corp.]

<<guy with  gray hair>>

Hi Bill,

Ok, Story time. I bought some 78 records (original Sousa Marches). It took 2 years to find a good 78 player. Well I did find a great German model (Dule?) that I know cost a lot more then the $5 I paid for it. It had a Audio-Technica cartage in it. Since I had so much invested in it I decided to splurge and replace the needle. It just so happens that Audio-Technica is a local Cleveland company.  Being the shy guy I am, I walked in the front door up to the big glass desk where the receptionist sat. I asked to see someone with gray hair. She gave me the look, the one I get a lot, as she hunted for the security button. Then said WHAT? I told her I need to see someone with gray hair. Ok why? (her finger is on the button) I then told her my story. I know the man for you. In a few minutes in walks a man, with gray hair, and looks at my cartage. Oh that's a 54678-44-A15b hold on I will be right back. He gave me 3 of the needles I needed.

Sometimes gray hair works.
