Among the many other changes to the John Bull were the 

 addition of a bell, a whistle, and a headlight, as well as a 

 dial-type steam pressure gauge (figure 32), and the reloca- 

 tion of the axle springs, the water cocks, the safety valve, and 

 the steam dome. At one time a cab was installed at the rear 

 of the locomotive, and an 8-wheeled tender was in use 

 (figure 33). 



The tender as seen today is basically original, but much of 

 the woodwork was in such poor repair that it was completely 

 disassembled in 1910 and stored, the rotted pieces of wood 

 being discarded. In 1930 the tender was completely restored 

 at the Altoona shops of the Pennsylvania Railroad Co., and 

 since that time has been exhibited constantly with the 

 locomotive. 



Prior to its presentation to the National Museum, the John 

 Bull had appeared at the Centennial Exhibition at Philadel- 

 phia in 1876, and at the Exposition of Railway Appliances
