I was able to run Compass 700x32c (clinchers) on my '71, but that was about the limit. FWIW.

It might fit if you take the droupout adjester screws out and put the wheel the whole way back. Tires on my 68 mesure 26mm and are abour half way in the droupot. At 2 or 3 mm infront of the tire the chain stays mesure 42 mm. Vittoria makes 28's in tanwall, tubulars ride better than clinchers for the same width

There's always something helpful to see in pics, saying this or that will work on bike X often goes a bit south as mostly no two are identical.

I don’t have any bikes that old but a x36 is big fat tire, hybrids and factory cyclocross bikes usually come with a x38.
have you tried a 27x 1 3/8 tire? Do you have any riding buddies who’s wheels you can try out? Are you on really good terms with a local shop? They might be willing to try it out for you, especially if you are interested in buying wheels from them.
BTW; where do you live? There might be a member right around the corner.....ok ok a few miles away willing to help you experiment

Hate to tell ya but you have a miracle setup right now if those fenders play nice even most of the time, I would not upset that setup.
Many here could never achieve those lines, let alone have them work long term.
Aside from that you will likely have to delete the fenders if you want larger tires unless you go with the 650's like you tried.

Gee, that kinda stinks. I can find Dugast and Challenge tubulars with road tread in 30mm, nothing any wider until you hit the Strada Bianca in 36mm. Kinda weird to me that there's nothing I can find in-between, especially considering how many high-end 32mm clinchers are available and sell, and how new road bike clearances have become more generous.
I get the "sewups ride more like wider clinchers" thing, but if I were a sewup rider, and my bike fit 32mm tires, I'd surely want a 32mm sewup that rode like a 35mm clincher.

I've gotta agree with @merziac. You don't wanna be changing anything there. It's your bike and all, and I understand the desire to improve on things (oh man, do believe I understand that) but this is not the place to do it. That is the kind of Paramount people have in mind when they throw around words like "grail." It's freaking perfect.
Find another bike, build it around that nice set of 700c tubulars. N+1 for the win.

Thank you all for the advice. I know you all have the best in mind when it comes to the preservation of a classic.
There's a trick that might be helpful if someone is wondering about tire fitment. It's so simple, I can't believe I haven't thought of it before, or haven't heard it from someone else.
I taped neatly folded paper around the surface of a wheel/tire combo that's close to my target size. In other words, I took a 700 x 30c wheelset and added width using the paper and tape. The calipers measured the tire at 30mm and I built it up to 38mm. The tires rotated fine with ~4mm clearance on either chainstay.
