Just got onto this site and thought I would respond to some of the comments. I am a Redfish crewmember but since I live in Arkansas I spent a lot of time on Razorback once we got her back home. The number 2 engine was removed in 1952 during her major overhaul and Guppy conversion. The #2 engine area was filled with equipment that was housed in the LL Control Room and the new Prairie Master. The LL Engine Room was converted to the Sonar Room, ECM room and part of the area is still the Machine shop with a lathe and some air handling equipment.
I believe the Turks took the Razorback out to sea sometime in 2001. We don't know how they could have dove her and brought her back in but they did. We had to replace over 80% of the lighting. The motor controller for the main supply fan was burned up, most of the heaters in the ductwork are burned up, the airconditioners would not hold any freon, the motor controllers for the air compressors are in real bad shape. Next April, a group of Razorback crewmembers will be back to work on the #4 engine and attempt to start it.
Razorback is now air-conditioned with 4 geo-thermal units using the Arkansas River as a heat sink. The air handling is done through the original duct work so you can't see where the units are tied in.
Razorback tour times are 1000-dusk Wednesday through Saturday and 1300-dusk on Sundays during the period between Memorial Day and Labor Day. During the winter from Labor Day to Memorial it is only open on Friday, Saturday and Sunday. However, any submarine veteran is welcome to come down anytime there is someone there to open the museum, which is almost always Sunday through Saturday. Also Submarine Veterans are admitted free.
Hope this answers some of the questions.
