The 1443/Coral/Dano was thin to begin with, and the neck is a baseball bat. I readily use Jasco stripper on -bodies- that look like badly painted basket cases (not necks). Hose 'em down with water? Yeah. Poplar has some good points- it doesn't absorb water (or stain) very well. Hey, you have to raise the grain anyway...
I've played maybe half a dozen different 1443's. Some original, some refinished many, many times. I've yet to come across a neck that wasn't straight. Any face/back bow issues were addressed by using different strings.
I love mine. I've done two salvage jobs on different 1443s over the years. Chasing down parts is the bugger.
There is a full set of original 1443 knobs, a neck plate (some didn't even have them), and a few other bits on eBay right now, btw. Not mine.
The repop Dano bridges seem more prone to bad sagging in the center, over time. I've not seen any sagging on an original bridge that couldn't be mitigated by some judicious shaping of the rosewood saddle.
