Some comparisons of shared sprues between kits:
Astoria, San Francisco and Minneapolis: E, H & J
Tuscaloosa and Vincennes: K & L
New Orleans only: D & E (E is common to the first three above and the NO may be a just a variation of the first 3 since E is only the main decks)
Conclusion so far- The Quincy probably matches the Tuscaloosa/Vincennes parts or is a variation of these with some extra parts.
BTW the A, B and C sprues are common to all the kits for shared items like the turrets, etc.
So probably getting closer but not there yet.
Thanks for describing some commonality between ships that I thought was unique to only one.
If you have all the other models, you could check the Vincennes kit. Quincy & Vincennes had the forward turret moved back some & the second turret raised a bit compared with the other ships.
Is the Quincy kit an exact duplicate of another Trumpeter New Orleans kit? I can rule out only the San Francisco '44 for obvious reasons.
Or: What are the sprue letter id's of the Quincy model parts - if you have the kit but do not know if it is a duplicate? (I have all the other NO kits except the Quincy).
Or: If anyone can post the Quincy Instructions that would be another option. Scalemates does not have them on their site.
FYI The Pit Road kits are reboxed Trumpeter kits.
