From the Hunnicut book: Photos of four T26E4s are in this book. Pics of the first two pilots, the pre-production vehicle and one production vehicle.
Pics of the T26E4 Pilot 2 (serial no. 97) vehicle show some items that HB has incorrect.
For instance, there is no phone box (B25 & B26) on the rear bulkhead nor the turnbuckles (G25 & G27) attached to the fender corners. No photos of Pilot #2 show the later, longer barrel lock -- although it's possible. Photos only show the "typical" T26E3 travel lock (B31), mounted to the exhaust housing. Omit H15, the equilibrator shroud.
The long barrel lock (H16, H18, H19), which attached to the rear bulkhead's upper edge -- was present on the T26E4 pre-production pilot and production vehicle pictures. Omit them for Pilot #2. And even on those, the exhaust housing is the older type with side "holes" to mount the previous T26E3 travel lock.
The HB decals aren't correct for pilot #2 either. They show the (I)pre-production tank and (II) the production T26E4 -- both shown in Hunnicutt. Pilot #2 had this text on its right turret side (row 1) "HVY TK T26E4" and (row 2) "90MM GUN T15E2". The photo of the left turret is more blurry but it can be assumed to say the same. Pilot #2 had a reg number of "USA 30119907" and it can be assumed to be along the mid fender stowage box.
