Thanks for the replies & the cool photos all
I'd love to keep it but I don't have the means & I'm maybe 15 years off having 5 year olds to force to play it.
The piano movers were impressive in action. Very nice guys & I'm jealous of them having another language to banter in (Tongan). That sure must make working in other people's spaces easier.
It's spent most of the 5 years disassembled, wrapped & in a non-temp or humidity controlled interior unit of a large storage facility. I had been thinking this long time would be when any damage would be done, and the 6 months tops in my garage wouldn't be as significant. The garage is pretty clean, and the climate here doesn't get that cold (last night was brutal for native Aucklanders but i still got a few hours riding in after the streets cleared of cars), nor will it get that hot until January. I will ask the tuner what he thinks about a dehumidifier when i talk to him today. It's sad if it's been damaged, but it's also reassuring to hear this is a keeper so even if it's damaged, we haven't scrapped a heirloom.
One of my best friends from High School is 2 years out of a Jazz degree from Auckland Uni, so he's pretty clued in. He said many guys could tune it well, but recommended the super expert who should be good help. He won't come until it 'settles' though. I'll know if it's a good player because my friend won't ever leave.
