Hi Gil,
Not that it matters but it was not me that was questioning the oil groove issue.
I am of a certain age and lack a certain intellect that makes me pretty much computer illiterate. So when it comes to the process of communicating on these forums I am not very comfortable or successful. So I do really prefer the simplicity of direct email, so I apologize for my downfall in that area.
Yes I have made a request on one other forum and have met with some success, however due to my dyslexia I find I can never have too many photographs.
I thank you for the time and effort you have spent, to this point, trying to help out.
Cheers...Carson
