Wanted: Early Weber Carburetors, Castings, Patterns & Drawings – DCO, DCO3, and 55ASI

I am looking for:

Complete carburetors, matched pairs, or rebuildable cores

Original or reproduction castings, housings, or unfinished bodies

Casting patterns, molds, or tooling used for DCO-, DCO3-, or 55ASI-type components

Technical drawings, reproduction plans, or factory blueprints related to these carburetors

Small parts such as jets, linkages, throttle shafts, and fittings

Condition and completeness are secondary — authenticity, technical accuracy, and detail fidelity are most appreciated.

I am based in Europe and can arrange secure international shipping and payment.
