I cant supply a pic, but theres a dead ringer for the 2017, sans tendr, in the denver forney museum. O and K too. Large balloon type stack with saw tooth edge, ob the rear , toward the cab, very river boat i think. Green too, if i recall.
Prototypical or not, i love these locos, if simply due to being one of the few tendr locos lgb offered.
And, imho, with a touch of added lead, great performers. Still one of my favs.
Of these euro / western versions,
I have 2 green, 1 black, 2 yellow, and one.....mauve...my fav. Np reason, really.
