Hi again Manch, Thanks for posting the pics.
Well mate, from the look of it, this will make a good restoration project.....it is a 70's model; with the vertical chain-case screws (earlier were horizontal) and it has the plastic front roller end-caps and the black plastic knobs on the grass deflector adjusters.
The cylinder reel has plenty of meat on it and doesn't look like it has been sharpened in quite a while.
It appears all original with the exception of the 3HP Tecumseh...the original engine would have been a 3HP Briggs and Stratton painted in the same 'International Orange' colour scheme (Same as the reel)
The sprockets and chains look reasonable for its age as do the chains.

We need now to come up a restoration regime for you to follow, what we need to know now is...how far do you wish to go? Don't worry, we will step you through the procedure and in the end, this machine will give you hours of mowing pleasure.
