I prefer the SC Knight. Let me know if any measurements are needed. I can maybe post pictures with measuring tape if that helps.
5 Dubrovnik Sets Comparison

I like the 1950 design the best and for that it's a tough call between Noj and Official Staunton knight. I go for Noj.
This is from Noj webiste:

It's certainly is mr M...that's your unweighted set right? What's the weight of the unweighted king if I may ask?

As I promised, here you are, This is the dubrovnik set I made, it tries to be a copy of the SC version and that's the final result. Maybe. in the future, I'll try to make my own version.
for those who like the fat rooks I made one but I don't know wich one to include in the final set
I think the knight is too small in comparison to the other pieces, so I started another one

Holly molly! Me likey very much!
If I may say something. I'd say the characteristic of Dubrovnik set are among others the broad bases so I'd say make the knight, bishop and queen broader bases, the pawn little bit broader base. Then either the king little taller or the queen little shorter to get the line straight (from pawn to king).
I'd say you're talented sir!
Jacmater’s Dubrovnik chess set is far superior to Chessbazaar and Staunton Castle which proves his unmatched woodturning skill

Wow, amazing job. In the picture with the 4 Queens what types of woods, stains and finishes did you use?

Thank you very much to everyone, the comments and compliments are very apreciated! I forgot to comment that in the pictures there are various attemps on diferent pieces so you see diferent sizes but the ones in dark stained are intended to be the definitive set. Taking a look again to the pictures I have to say that I agree with you in all the comments you posted.
Pawnerai, the first time I saw the fat rook I thought it was ugly but the more I watch it the more I like now (and that will be the winner :) ).
MCH818, totally agree with you, too, the bishop and the queen are too high in relation with the other pieces.
The OneCalledMichael, that's something I realised when making the pieces the knight, bishop and queen need wider bases, the king base is the right one in my opinion. The fact is that I made it just for fun and to have a dubrovnik set.
KineticPawn, I forgot to give technical details!! All the pieces are made with cherry wood except one bishop that is made with boxwood (forbiden wood for a dubrovnik )and are stained. There is one queen in raw cherry just varnished (not polished) as I'm trying diferent finishes. The pictures you and Fluxblunders posted helped me a lot, thanks!

I can't wait to see the final set. If I were to play World Championship next month, then I would have demanded to have your set as what is going to be used
Keep us posted about your work, you're doing great job!

This is from the Noj website, their 1950 Dubrovnik repro.
When I saw your black pieces it reminded me to the above picture.

sooooo...practice practice practice practice !! hahaha.
I'll keep you update of the progres. As KineticPawn suggested, I'll use maple for the white pieces instead of boxwood (it would be very strange a dubrovnik in boxwood as well as in ebony, I think)

The queen and bishop are too tall by a bit, also queen bishop and knight could use a bit of an upgrade in the base width department. Fat rook all the way, although the one you made resembles more closely Noj's 1950 design. I'd go with just a tad smaller ball on the pawns to give the set a slightly more delicate look. Either that or make the collars a bit wider? Great stain results and overall great looking set.
I am curious because I research dubrovnik chess sets for 5 years now
What did you find out?
