Moto Guzzi 850 Police Eldorado Siren Lever assy NOS LAPD

I believe Guzzi's number for this lever is 1360-6840.  Apparently police sirens on early Guzzis were cable actuated. (How in hell did they drive it? From the rear wheel or something?) Condition is PERFECT. Any discoloration shown in the photos is only preservative.
