It's a Williams Casanova with missing backglass. And lock down bar, but that's not a problem.
Quoted from Daditude:
Maybe I'm wrong, but I felt the OP was referring to whether or not it was 'worth' it.
When words like valuable, desirable, and expensive all come into play (as they did in the opening post)...I have to assume that is the case.
Of course, if anything is a personal pursuit, a certain self satisfaction could be derived...even if you have more into it than it is worth.
It's a bit of both. I don't think this machine is particularly desirable or valuable (despite the unusual bagatelle in the head). If the backglass was there and decent, I wouldn't even think of this as a potential parts machine. I'll put massive time and effort to save a machine and have done it many times in the past, and thoroughly enjoy that part of the hobby, but the question is wider. I've come across other less desirable (often non-big three EM manufacturer) machines that are missing the backglass and no one is reproducing one for the particular machine. What happens to those machines? And, if I could find a backglass for the Casanova and it was $300, would I do it? Not sure.
