It is not so much being a "purist" but preferring
to not stick out like a sore thumb when playing with other instruments.
12TET and close to dry works with nearly everything
If I had one box for everything including Cajun and Irish and English and French and Quebec.. it would be tempered tuning and close to if not dead dry.
Thanks again for your great comments. Just an update, I bought the 112, a very sweet instrument and cleaned out the bellows of the 114, which has improved its playability greatly, plus largely removed that nasty smell! I also got a quote to replace the damaged bass reed on the 114 for $130 (parts and labour), which sounds reasonable. That means that for less than $400 I'll end up with two fine sounding Hohner one-rows. Now that's what I'm talkin' about...
