I'm looking at the the keyboard layout for this keyboard (https://www.modelfkeyboards.com/wp-content/uploads/2016/01/2...), and it doesn't appear to match any IBM keyboard model. It does not resemble at all the original Model F (https://upload.wikimedia.org/wikipedia/commons/5/56/IBM_Mode...). It is closest to the keyboard that came with early models of the PC AT (https://upload.wikimedia.org/wikipedia/commons/3/38/IBM_Mode...). The placement of the function keys, control keys, etc. is quite different though. What's the point of calling it a model F keyboard if all it shares with the Model F is its key switches?
