In all likelyhood, they are for replacing the dynamotor in the T-195 
transmitter.  No bearings and brushes to tend,  far less inrush current 
on startup, but the transmitter is still almost as noisy. Despite what 
it may sound like on the air, a T-195 user is probably not catching up 
on vacuuming while on the air!
