It's such a unique application of the material. ------------------------------------------------------------ More to the point is the fact that they had no expectation their pianos would still be in service 75 to 100 years later. The knew full well that the musical performance they built into their pianos would dissipate over the years and that no reasonable musician would want to play them after 20 to 40 years and that they would then be discarded. The brass rails would easily last that long no matter how they were made. I suspect that most of those manufacturers would be appalled at how low our musical tolerance level has become. And now I suppose I'd best get in my rush order for one of those glitzy new, completely redesigned and greatly improved flame suits. The deluxe, extra heavy duty version, if you please. And ship it Overnight Express. Thank you. Del
