The third type of air cleaners was the more conventional “Coffee Can” model. They used a satin black painted steel top and bottom with side panels made of louvered aluminum or perforated and nickel-plated steel. The earliest ones had the Weber information embossed in the top but this was soon replaced with a smooth top using the same Weber tag riveted to the top. Early “Coffee Can” top Weber tag.
In the early 1950s the “street” cars used three of the two-barrel Weber carburetors. The air cleaner assemblies were supplied by F.I.S.P.A with a small aluminum F.I.S.P.A tag riveted to the tops. Two-Barrel early regtangular F.I.S.P.A air cleaner tag.
