Curious about Scamp Jalousie windows, wonder if mine are original?
Vintage Scamps, up to around 1984, had silver-colored, milled aluminum jalousies. In 1985 they switched to black painted radius sliders, which were standard up to around 2010. In the 1990's and early 2000's, not sure of the exact years, they also offered the non-radius, black-painted jalousies as a factory option. That's what you have, and they're not too common. Around 2010 or 2011 they switched to the current radius jalousies, where only the center part swings out.
Yours is one of the oldest I've seen with the jalousie option, so I'm not 100% sure whether it's OEM or a retrofit.
They're nice in either case! Great for ventilation even in the rain.
