Hi Richard.
I don't doubt it in the least.
I do not know how much documentation on these vehicles Colin has at his disposal, and with many parts missing completely, or very badly corroded, trying to interpret what one actually has and can see, in relation to any existing documentation, can be a challenge.
My thinking was to try and come up with a way Colin could inspect what he has and relate that to a gear that was getting physically worked over the years. Don't want him to get a massive headache and stop posting for a while. His great work is way to fascinating!
