Nice of you to join us, James, indeed.
I want to offer a quick word of caution about that 605 1/2. There have been
a variety of counterfeits made of this particular model that require a
significant amount of time and expert effort to detect.  I'd be happy to
inspect it if you like.  No charge, of course, but it would help if you
paid postage. Convincing an elderly pensioner to pack it and pay postage in
your stead would also suffice.
Enjoy your days, all,
cur
