@ Delaphonics: are you sure this is a Gazelle? Strange dropouts and ends of seat stays and chain stays for Gazele. Not sure about seatlug either...
Check below BB shell.
@ Dicki: I used to be designer /engineer.
Yes, some nice frames came by.
Best frame: hard to say.
Basically everything from A to AA-Special was pretty much the same. All 531C tube sets. Fork blades not all the same and bits like BB-shells and fork crowns were a bit different (sheet metal vs. cast). But differences are mainly emotional. Quality wise pretty much the same. Difference cannot be felt.
Fabrication was very much the same for all these OTP frames/forks.
Only custom (size) frames, 753, cross, track, tandem, were complately made by hand (1 frame builder one frame) and not in series.
But even then: not possible to say which one is better.
Perhaps the AA-Special was the best in all it's simplicity. The rear brake cable through the t/t was a bonus, but you could even argue about the (added) value of that.
My last Gazelle frames were AA-Specials with 2 brake cable stoppers on the top tube, a Shimano cable guide below the BB shell and 2 rings for STI shifter cables on the lower head lug. All made to measure with dedicated geometries.
Now I would love to have a 531 or 753 Gazelle track frame set in 57/58 or 59 cm.
