When would that have been? Are there a bunch of Gulbransen verticals out there somewhere that are a month or more older than these that have steel wrapped bass strings? Has anyone seen one? Hands? If it's design change overlap, how about the other interim pianos with 9 leftover steel bichords, then eight, then seven? As for the leftover strings found in storage and installed rather than let them go to waste - that must be it. Surely a manufacturer would take whatever time and effort was necessary to cycle obsolete parts back into the updated production run so they could save the $0.25 per piano it cost them to make those strings so they could be lost in storage. In fact, there are probably an equivalent number of more expensively produced copper wound strings in storage somewhere that were displaced from the assembly line to accommodate the use of the old steel wound foundlings. Just think of the income opportunity here for someone with the ambition and resourcefulness to track down those leftover copper wound orphans and travel the country retrofitting all those old mistreated Gulbransens to restore them to the original glory they were deprived of at birth. Now I don't need to know badly enough to drive 50 miles and spend an hour taking scale measurements which may or may not tell me anything in the final analysis in any case, but I really am curious to know why they went to the trouble to put steel wound strings in one bichord unison, surrounded by copper wound bichords. It had to cost them more to do this, and I'm a firm believer that a manufacturer isn't going to waste a nickle without a reason, so why was it done? The only thing I've come up with by way of speculation is that they might have had a longitudinal mode howler there, possibly accidentally designing in the worst possible dimensional combination, and settled on the steel wrap substitution as a more expedient and cheaper alternative to starting over with the scale design. A sort of post-disaster back patch. I just wanted to know if anyone had any information on it. This isn't an earth shaker, I know, but the information has considerably greater potential for future usefulness, to me at least, than Glenn Gould's taste in pianos. Not that that isn't informative. It is, just not useful. Ron N
