I am putting out a request for information, I am currently restoring my Gambler 510 and having been in talks with Switzerland regarding replacement parts I have come up a blank obtaining any information on the following parts. Steering wheel hub (dimensions and detail), steering system (this I know was a solid bar system but no details as was thrown away before I got the boat) and the throttle and gear change (no details of the handle or any thing)
So I would like to ask if any one has any photos or details that would help me restore this beautiful craft to its original condition.

Many thanks
