Window operators for 1972 to 1974 Bolers and mid- to late-70s Triple E Surfside fiberglass trailers. Also used on some canned ham trailers like Prowler, Ventura, Taurus and others.
There were dozens of sizes and configurations of torque bar operators used through the years on vintage trailers. It's really hard to find the right operator for each type trailer. Here's one we are sure is right. If you have others you know of, let us know.
