Hello Sbtragic A warm welcome from me to these forums. Yes, this is Model 45 central I would say.
I have fixed your great gallery of images. The main problem was that camera resolutions are too big for the internet. This is in both file size and dimension.
Our 45 expert - Bonnar Bloke - is absent for a few days. In the meantime I can offer my thoughts...
This looks like a sound machine. I totally agree with your view about paint colour. Mr Jones' work and choice represents restoration at its best.
My main objection with this Kermit Green colour (used by Rover) is that the process has proved so bad. This isn't paint as such but a very poor powder coating. We do not recommend this process for many hard wearing bits on lawnmowers.
I don't think the engine is original - as it has on-board throttle and choke controls. Original machines would have had a remote throttle control. It presents as an off-the-shelf replacement motor.
BB should be able to comment further on his return, shortly.
I attach a couple of images of an original spec machine like yours. Note the lack of on-board controls. Also note the difference in the deterioration of the paint between the first and second machine.
