Axis29, I like all three of those Tweeds; and I have owned an all-original 5F1 from 1957 that was closer to the color of the amp on the right than to your shellacked amps...which have colors close to all-originals I have also owned or seen. Ime, the vintage tweeed amps come in all colors due to differences in their environments over the years. Just like lacquered guitars, less light means less yellowing and vice-versa. Same with tob@cco....a lot of exposure to tobacco takes tweed in another direction. Some of them are almost brown...a very golden, transparent brown thing.
