I am keeping my eye on the 'bay constantly for a cheap Crown Graphic. I don't even need it to have a lens and the bellows can be shot since I have practically new Crown Graphic bellows here that I will more likely use in my own build because I won't wait for years to start shooting 4x5. Unfortunately, even the moldy, lensless ones are quite highly priced and some even marketed as in working order. And living in the middle of nowhere means no Craigslist for me. I don't know if I have said it in this forum before but the analog gear aftermarket here is pretty much Smenas and Zenits going for hundreds of Euros. Sold by old ladies as relics from the Soviet occupation.
