This Unadilla silo has always been indoor thus preserving it original patina from direct sunlight. I don’t think it ever had a cap/roof on it. All the doors are still there along with original metal banding. Only three some inches will be needed to be trim off on bottom of silo. This silo would make a stunning observatory, spiral stairwell, lookout tower, etc.
Date: c. 1920 - 1935
Species: Doughlas Fir, Red Pine, & possibly some cedar.
