Partnership related question

Hi Dear Lawyers and experts, A Partnership firm was constituted in the year 1985 namely " M/S Universal trading" with 3 PARTNERS. Name of three partners: Ajay Singh, Ved Singh, and Piyush. In 1986, commercial land was purchased in the name of the partnership firm " M/S Universal trading". In 1990, Ajay and Piyush retired from the Partnership firm by signing a dissolution deed and transferring all the assets in the name of Ved Singh. Now Ved Singh is the only one partner of M/S Universal trading partnership firm with all assets and liabilities. NO CONVEYANCE DEED/ SALE DEED IS EXECUTED AFTER THIS by any other old partners. 1998, Ved Singh made a new partnership deed with 2 new partners and opened the same business with the same name M/S Universal trading and in 2000 Ved retired himself from the partnership firm. Ved Singh hasn't put any land in stock in the new partnership agreement. My Questions are: Who is the owner of that commercial land now as it stands in the name of M/S Universal trading? Is the old partnership firm dissolved?
