A 1951 Cruisette came in for window work. Front window first: a quarter-inch gap and seals gone rock hard.
These are first-generation Royal windows built by Associated Pacific — the same company behind the Air-O-Lite windows on 1947–49 Airstreams. They get called Hehr windows; they aren’t. The whole assembly is a sandwich bucked into the skin with the gasket trapped inside, so the gasket only comes out with a full disassembly. Screen included. This one had been set in plumber’s putty, cracked and sealing nothing.
I drilled it out and took the frame apart on the bench. New gasket. Wire-wheeled the hardware and coated it in POR-15. Three of the four tension bumpers were missing, so I cut new ones from aluminum. New aluminum screen. Set it back in the skin on oversized rivets.
Seventy-five years had petrified the gasket onto the glass, and both original panes broke — one coming out, one later on an existing rock chip. Clean breaks, fine to travel on. The trailer was due to go camping, so I buttoned it up. The rebuilt hardware and the new bumpers work and the windows latch down hard for the road. Lower glass when it comes back.
