[TPIN] Bach question

[David Johnson]

Sorry I wasn't clear but yes, I did that and each second valve slide fit
perfectly in all three horns.  Another oddity here is that the serial
number on the large bore horn is not stamped horizontally on the second
valve casing above the slide, but vertically on the opposite side of the
2nd valve casing (away from the slide) and the "L" is stamped at the
bottom of the 2nd casing below the slide. I've never seen a Bach Strad
with this configuration before.
