NOS Tommaselli Super Pratic B Throttle for 7/8" Handle Bars.
Throttle is complete with damper and securing set screw.
These throttles were made in the 1960's and may need a bit of polishing to look there best.
Some throttles have the white plastic grip washer and some have metal washers.
NOTE: Throttles will need to be disassembled to clean out the 40 year old dried up grease before using. Throttles are NOS 1960's production original Tommaselli.
