There may be more to this than you think. This is not a chrome horn, ...or at least it does not appear to be. This is a hand-made, hand-spun stainless steel (-not chrome) horn. If we think back to the Allegheny Steel built 1931 Tudor Sedans that were built as the promo for Ford, -with only one surviving today, this would be a great start on cloning one of those Stainless-steel Sedans. While the price may not be for everyone, ...it definitely is not out of line for what it is in my view.
