R1 head won't fit, Graham, so good job you didn't accept that offer.

Depending on how much you paid originally, you should stand a fair chance of recovering most of your outlay over time as you dispose of the bits.  Alternatively, take your time in sourcing a replacement head and rebuild ... however, from some of the other issues you've listed here over the past few months, probably best to let it go as spares.

I look forward to seeing the new one in a few weeks ...
