Sprocket Shuffling/Building a Cino Freewheel
I am sorting out the gearing on the bike I'm riding in Montana next month. First off, it has a 144bcd crankset with 52/42 rings. I would like to have a 32 tooth sprocket on the freewheel
I have a couple of 6 speed freewheel a 32t. However, they're standard width and wont work on my 120mm spaced wheel(without spacers and possibly a longer axle). I do have a nos 13-21 Ultra 6 new winner freewheel, along with a 28t and 32t sprocket. I also have a 5 speed winner freewheel(13-26).
Are these two freewheel interchangeable as far as sprockets go? Ideally, I would like to turn that Ultra 6 into my Cino gearing. This would be my first time tearing apart one of these things, so I am asking you the experts for some help.

Have you been shown the New Winner freewheel literature and cog board layout?
It's got the info about what cog types were used on the various configurations. The configuration variations include ultra vs. regular spacing, and whether it was 5, 6, or 7 speed.
the literature:

and the "service board", which is how bike shops stored and displayed the spare cogs and spacers.

You'll need to figure out what cogs and spacers you have, and then figure out what you will need for the desired freewheel.
For SunTour freewheels that aren't New Winners, the cog arrangements will be different.
It's possible that you'll want to take them apart to see exactly what you've got.

The Winner pictured is the original Winner. Notice there are no little holes spaced 180 degrees from each other. I've only had a few of these in my hands and I could never service them. However, the sprockets and spacers should be interchangeable with the New Winner, and vice versa. I'd personally use the New Winner body over the original Winner body.
You should be able to remove both sets of sprockets and mix them together with the 32T onto the New Winner body, as long as you only use either the Ultra-narrow spacers or the standard spacers. You should still have a 120mm compatible freewheel if you use the Ultra spacers.
With that said, I have switched wheelsets on my '71 Paramount. One wheelset could run an Ultra spaced Suntour freewheel, while the other wheelset did not have enough clearance for an Ultra 6 speed and could only handle a 5 speed.
Finally, I have found that Ultra 6 speed freewheels prefer a narrow 8 speed chain, such as a SRAM or KMC model for improved shifting.
Hope this is helpful.

At least for my gravel riding, a 52/13 top gear never comes in handy, so I'd probably lose the 13T in favor of a 14T or 15T, or shrink the big ring in order to free up derailleur capacity.

Unfortunately, ThermionicScott if all Roger M has on hand are the two Suntour freewheels pictured, he only has a 13T for the first position on those two bodies.
I agree, for Cino, I'd probably run a custom Suntour Perfect or ProCompe Ultra 6 speed with a 15T or 16T high-gear.
