Curious to hear your story. PM will be fine...
Here's mine. It's a very positive experience, so I don't mind posting it for all to see:
I bought a rebuilt TR3 OD gearbox from him. Worked great until I broke a tooth off the layshaft 1st gear. Decided to repair it myself instead of ship it back to the deep south. I had a spare gearbox with the right part in good shape.
He offered to repair it, despite the length of time that had elapsed, and the fact that a broken 1st gear is more likely user error than a warranty issue. As I had the thing apart anyway, I was tweaking the OD performance. We had a couple of phone consultations. He sent me a modified actuator valve, a NOS accumulator spring and some gaskets -- all for FREE. All I had to do was send him the actuator stem I was replacing.
In sum, with me, he's been a straight-up cat who has gone further than he really needed to to make me a happy customer. Sorry to hear that this seems not to be the case with you.
