General Information
All steel construction except pivot cap (aluminum?), butterfly nut (white metal alloy?), and knob (plastic). Odd braze-on mount; unit received as shown, possibly missing some internal spacer hardware due to the inability to provide proper friction adjustment for lever. Exploded view is in order as received, it might be incorrect. I believe this unit is from 1959 (late '58-'59) since it utilizes the 'wreath' logo design the same as used on the 1959 rear derailleur.  Cage width is 11mm internally. I have never mounted this unit due to not having a frame of the same period with a braze-on tab; nor have I seen a frame with this unit installed.
