You might ask Don where you can get it serviced if/when the time comes. It is my understanding that Don is, at least, semi-retired. I’m sure he has a legacy plan for this stuff, but it’s good to know when you’re looking to drop a substantial amount of cash on a rather bespoke / boutique piece of gear.
Sound advice. Thank you. I hadn’t considered it in this case but service is one of the reasons for my interest in point to point. Kara Chaffee, in a kind response to a question about her de Havilland Ultra Verve, said “they are pretty straightforward and accessible to repair.”
