50cm vintage frame (with 59cm top tube) for 1m75. Does it fit?
My favorit vintage frame has 50cm seat tube and 59cm top tube. As many charts from google.com, 54cm frame size is the best fit for me (1m75-80cm). Otherwise, the long top tube could make a balance for me with the short seat tube.
Is this frame still too small for me?

It's a Blind guess on a text site .. use the data you can find and make a Full sized cardboard replica?
I built a 58 with a 60 top tube , the center of gravity, wheel further from it, makes it's general handling feel lighter, steering,
now I have a Porteur rack on it so the load takes care of that..

Based on my result from argonautcyclecoaching.com's calculator:
Seat Height: 68.6cm. So i need to raise saddle about 15cm
(Top tube + Stem)'s Length = 63.5cm. So i need 4 or 5cm stem
This website has writed: "The frame size should be selected based on the top tube length rather than seat tube length..."
I'm just wondering others' experiments could prove them right?

Or they just stretch the toptube dimension so your feet dont hit the front wheel at low speeds, turning.

Maybe, who knows technology's ideas from 70s . If i have the same shape 53cm frame, i will have to reach out far even with 1cm stem.
