Thanks for your replyes
As some of you have guessed, the car I have bought is Jerry's, and it looks as a very nice Cobra in good shape. Due to strikes in Los Angeles ports the car is not yet shipped and I have only seen pictures. I really look forward to se it live
Jerry is convinced that it is a Butler, but when I talked to Ron he is sure it is not build in his Workshop. He has not used this frame no. (he use BR) and he say that the missing water rails in the body in engine and luggage compartment indicates its an Arnzt.
According to the papers its build in 1979-1980 and has been on the road from 1981. So this is arround the time when Butler and Arnzt broke up.
As far as I understand Butler took over after Arnzt, but I don't know how much they worked together before they broke up, and if the cars in a period was more or less identical?
I have attached a few photos if this can help.
