Hello vint-mow and Mowerfreak I think you are pretty close there. ... It's a Rover by another name.
My best guess is that this is a Fairway catcher dated late 1960s or very early 1970s. Most of the big makers changed to plastic catchers by the new decade, but some did not (Pope), and some kept steel catchers on specific models (like Rover Model 14 and 32 side discharge mowers).
Like Mayfair was to Victa in the early days ('Victa' did not appear on early Mayfairs), the Fairway was Rover's stencil brand in the 1960s ('Rover' did not appear on Fairways). Fairways were originally 'toe-cutter' utilities, but later were offered as rear catcher models.
Note that a steel catcher was still being used on the standard Fairway in late 1970, whereas the Fairway Deluxe had the newer plastic catcher.
Hope this helps. ------------------------------- Jack
