Somtimes you can indeed go to from 2nd to 1st at about 20mph, somtimes you can't
Just don't force it.

Actuallty, it is the syncros trying to do its job that is preventing it fom easily going into 1st and it is just the nature of them.
They can oly do so much so don't force them as thery are relatively delicate parts. They can last the life of the car if treated with respect.

If your syncros were bad you would hear gears grinding when tring to go into gear if your shafts/gears were not spining in sync.
Before the invention of syncros, shifting was an art forn and you had to manually judge was everthing was in sync. It took some skill.

You would hear a lot of gear grinding at times from inexperienced drivers and people would shout out things like "grind me a pound", etc.

Haha, that reminded me of that one Star Trek episode where Kirk and Spock are driving that old car.. Classic

"Rev matching" is an old technique known as "double clutching." Push in the clutch, move the shift lever to neutral. Let the clutch back out. Give the gas pedal a nudge to bring the engine revs up to what it'll be in the lower gear you're shifting into. Push the clutch back in and shift into the lower gear. You don't bang anything, but it's all done quickly. Takes practice.
