The Galveston maritime museum had SS Elissa in her "sailing barque" glory. They were not really operating her as a museum, per se, though.
The museum side of the operation did/does have quite a lot of documentation of the stages of Elissa's rig and fitting-out. She had been a barque, a barquentine, right through to her condition when she was "found" heading to the ship breakers as a mast-less M.V.
Sadly, while having ridden out Ike almost unscathed, the last hull survey caused her to be de-rated for carrying passengers. (The volunteer crew are carried as supercargo passengers for legal reasons.) The iron hull and frames may prove a dilemma for Texas Seaport Museum.
Since all of her rigging was restored "from scratch" (adn to present USCG requirements) it's rather unsuitable a a historical reference. The reference photos and documents in the museum do not suffer that deficit.
