Caterpillar,
Like I said to Dick, it is not very meaningful ( apart for yourself of course - or for me speaking for myself) to make these comparisons since there are so many factors involved. When comparing old or new or later made instruments just THAT makes a great difference itself.We are talking about mechanical gadgets victimized to wear and tear.My own experience has been that many of those later made instruments in real have been a lot better for musical performance than even more originally exclusive ones.Being a Wheatstone fan I have for instance been able to compare quite a few Aeolas from the "golden era" pre WW1 with usually demeaned models from 1940s or later and I can not agree concerning the assumed superiority of the earlier, either because they have been violated by later processing or have needed a complete reconditioning to even up to the standard of a later product.You have to compare real "twin" instruments and I have been lucky enough to have had half a dozen of different twins to compare ( some with consecutive or near so serial numbers)and some which have been seemingly exacly alike have sounded differently.
This you come across even with new made pianos etc.
