RARE Large Antique Weston Laboratory Model 326 / no.1492 AC & DC Wattmeter. Measures 15” x 14 1/2” x 5 1/2” tall. This is in as found untested condition. I am not sure if it still works. Everything seems to be in great shape for age. No chips in cracks in glass. A very nice early piece of scientific equipment! See photos for details, any questions feel free to ask. Good luck bidding!
