Measurement of Q-factor with modern hardware ?

Apart from the low MHz, what I've read about this device is pretty adulatory.

It's almost unthinkable that a device from the 1950s would exceed anything available today!

How could this be?

May be of interest for antenna stuff:

I wonder if a noise bridge would be useful? I built one that Joe Carr published in one of his books and there are certainly some online. It's a pretty easy device to build, needing just simple RF toroid plus a couple carbon pots and small caps. The noise source is a reversed bias base emitter junction of various common small signal transistors. You need a receiver, but if you're building antennas, you probably have that. You can also buy one ready to go for very little. IMO, better than any LCR type device because it gives you the values at the frequency of interest.

Will do that, thanks for reminding me! (Noise bridge)

Maybe as weekend fun. After fun with noise bridge you better build better VSWR device which is more up-to date, something like this:
