Hack, The one the right is not from a 175, 200 or SL350 as they use bolt on carbs and that's a spigot mount. Plus it's not a CV which was used on SL350's after the K1 model, plus it's a Mukuni, honda used Keihins. The one on the bottom is interesting....looks like a really old Keihen CV carb...maybe from an early model CB350?
The top one looks like a late model Honda 50cc or scooter carb.
PS. I'll only charge $5 to throw them away for you
