Hi Ian
I am in Canada, so different time zone, and I was away from the computer yesterday anyway, so I am just seeing this series of posts now.
First, please stick around, you obviously love Laverda's. You never know, help may even be available from various forum members. Certainly getting the word about concerning the vin is a great first step.
Steve Winterton used to be an active member of the various versions of what has evolved into this present Laverda Forum here, then there was a huge blow up that involved both Slater brothers as well as Piero Laverda and others taking issue with Steve Winterton, which blow up sucked up an enormous amount of my time as a Forum Admin dealing with all the parties behind the scenes off list trying to discern facts, balance various interest, and resolve matters without litigation amongst the various parties and stave off threats of legal action against the forum itself. Ultimately Steve voluntarily withdrew from the forum, his son Tony stuck around for a while and seems a very nice fellow, but I have not seen any posts from Tony in quite a while, unfortunately.
I have met many of the UK based Laverda forum members during two recent trips to the UK, but have never met Steve Winterton, so have no personal experience of him
In real life I am a senior litigation lawyer in Calgary, Alberta, Canada. If I were in the UK I would have been happy to evaluate the facts and potentially assist in recovery efforts. I can't be of direct assistance due to geography and jurisdiction. I am familiar with the perils of bringing legal action against someone if they do not appear to have assets to recover from, if that is the case here. There are also limitations issue that may have arisen with the passage of so much time, but for the present value of any SFC it would seem to me to be worthwhile to gather all your facts, including your ownership documentation, and consult a senior lawyer about recovery options.
If you have issues with what anyone has posted on this public Laverda forum, these days we have several admins and I saw at least one well worded response to you from one of them, however I would ask you to feel free to contact me directly at pleclair at hotmail.com before sending direct communications to other members concerning potential legal action, etc., and give me an opportunity to attempt to resolve what ever the issue may be concerning other forum members. While we run a fairly "relaxed" operation compared to some other forums, we do have basic rules and we do intervene as may be necessary, it just has not been necessary very often.
All the best
Paul LeClair
