Grip and joystick from AT-6 Texan

We purchased this set as an unidentified aircraft stick at auction with no idea what it came off. We have subsequently been advised it would have been from an AT-6 Texan and is fitted with a US or Canadian made grip. The numbers stamped on the reverse state 73-61044 and separately IO. The Texan (or Harvard as it was known in RAF service) provided an advanced trainer capability for pilots of the United States Army Air Forces, United States Navy, Royal Air Force and other air forces of the British Commonwealth during World War II and into the 1970s. The grip is in generally very good condition although the paint has been mainly rubbed away. The gun button which seems to be some sort of alloy rather than brass is marked "safe and fire" and the back of the gun button is marked 66-61179-2. The grip cover is in generally good shape but one area of damage but when viewed from the front, it looks perfect. This one came complete with stick which is marked 52 52103 which has also been identified as Harvard. This is in the original paint and is in excellent condition. The bolts to secure the grip to the stick are missing but the holes line up exactly, although we can't say for sure that this stick was used in conjunction with this grip in service. Measures 34" (87 cm)
