14 inch scott bonnar 45 by the looks
I am fairly sure the 14inch was long dead by the time of the red colour change. (1990s).
May be able to give you some of its history though.
Given a few identifiers (which could just be shear coincidence) I would dare say it could have been one of the many hundred (over the years) SB mowers restored by Les Smith.
He ran Les Smith Mowers in Malaga and did a lot of quality SB restos. A lot of them in that red regardless of original colour.
Additionally, all the ones I have seen that he had done nearly always were missing the ID plate (would fit on the 2 holes under the clutch cable in picture 2).
The only thing is he would have never done the catcher like that with rivets.
That motor is a 2002 build by the way.
Here is the link to the clearance sale photos when Les Smith retired in 2016.

I would stick with that sticker pattern - though its technically a Scotty, not a rover riven age
