I don't know what the problem is with Pegasus. A few months ago, I contacted them about some screws to hold an ignition switch in place on a Series 3. Paul very kindly put 3 in the post almost immediately and sent them to me F.O.C.
I went over to his house to meet him some years ago with the remains of my Lightweight 2A bulkhead so that he had something to template a replacement. I found him to be a thoroughly friendly, knowledgeable and helpful person. However, judging by the comments on multiple forums (or should that be fora?) far far too many people have come unstuck with dire communication and payment issues. Given that what they build is good and the parts they sell are generally very useful, I can't understand why it always seems to go so wrong.
I'm tempted to drop him an email and ask for an explanation. There has to be a reason why this is happening and if the company (I think the parts business is a partnership as opposed to the bulkhead business being a limited company) perhaps he should be given an opportunity to explain why there are so many complaints of poor service and non supply of parts. Frankly, if he were deliberately trying to defraud people, surely its a bit stupid to run the business from one's home address and provide his and his wife's contact details on the website!
