Hey Tyler - thanks for posting a pic of your serial number tag. Pretty certain you have an original 800 production unit that was built around the end of Feb. 1975.
The reason I say "pretty certain" is that the info I have shows the Model 800's could have IH Product Codes 2050050, 2050510 and 2050520. Yours is 2050052. However, over the years we have discovered the same issue with some of the other Quiet Line Models having the "0" (zero) mis-placed/transposed in the list of Product Codes. Not sure where the original listing of IH Product Codes resides (maybe in the Wisconsin archives). Maybe Kraig, Oh Great One and Keeper of the Photos, has more documentation info.
