Isn't this now the ONEGas Tower? 64.207.238.106 ( talk) 21:28, 20 November 2014 (UTC) reply

The registration form for the Oil Capital Historic District listed the First National Tower/Chase Bank at 15 East 5th Street and stated that it was constructed in 1949, and classified it as a supporting property for the district. More recent sources say the building at this address was constructed in 1973, This apparent discrepancy should be clarified with a source. Bruin2 ( talk) 19:04, 25 December 2015 (UTC) reply
