01/31/2013. Remarks by Johan Visschedijk: "Here a Robin J-1 is pictured, converted to a crop sprayer, with clipped wings and re-engined with a war-surplus 220 hp Continental R-670 radial engine. The converted aircraft received its CofA on September 16, 1952, and presently still has a valid registration. On the left is another Robin J-1, also re-engined with a R-670, registered N780M (c/n 681)."
