The blue air cleaner a couple posts earlier is reworked for modern paper air filters. The welding and grinding caused it to look unsettlingly rebuilt, but a few squirts of black, beige, two browns and another black got the patina started. Dousing it with sand and dirt and scuffing it with a rag while the paint still wasn't completely dry, made it look suitably old and grimy. The rust on the very top of the cleaner is real original rust. ( I thought I'd never be proud to say that *grins*)
The color is better too, it doesn't look too much out of place now.
A piece of 3" exhaust pipe happened to fit the Rochester 2G nicely, and was used as a base for the air filter rebuild. Two small paper filters off a Tri-Power setup was used.
