I have been working with the Iseki factory for the last 5 years. They have not used that nose during that time nor have they used a 12x12 mechanical shuttle in years. MF used that sheet metal back on the 1100 series in the early 1990's and when they moved into the 1200 series the 1165 was added. Yes, the hood panels are the same style as an 1165 but the nose is of an older Iseki tractor. It was not from the 2000 and later year era. The new Massey's (1500's) are based off of the TG tractors, which are the domestic tractor used by Iseki in Japan with some changes to make them fit the North American market. They had been exporting TK's to countries like Austraila but are now moving to export the TG series instead. Confusing I know. Anyways, several parts are going to be similar. If you have a model and serial # I can see if I can find out exactly when it was made and to what model it would be closest to.
