After Photos: Yamaha YBB-641 Tuba

The after picture above shows an installed #4 lever. This particular Yamaha Tuba is a 3 digit serial number which makes production between the late 1970s to the mid 1980s. The original #4 lever is obsolete. Luckily for me, I had all of the other parts; stop arm, linkage and various screws. I retrofit a modern YBB-641 lever using a french horn linkage ball socket to connect the new lever to the old style linkage. 
Due to the angle of the photo, the above after pictures may be hard to see.
