Does anybody know if the Holton 140 with the tuna can valve had also a narrow slide or did it come with a wide slide?

BTW: 150`s and 158`s have a different slide with. The 150`s slides are even a tad narrower than the 158 slides which are exactly as wide or narrow as 88H slides.

I only know that the straight 156 and the 159 (both 547-562 dual bores) had wide slides like a Bach 42.
