I think if you want help you really need to make it clear if you are going to keep it in tractor form or put it back as a roller.

If you go down the tractor route then there are no 'original bits' so it is difficult to know what you want. If I had some F type bits I would rather see them go on to a roller than a conversion so I would hold back.

If you put it back as a F type then there are plenty of bits around and I for one would like to help you find them.

Any news on this restoration

Missed this thread the first time!
Your engine was ordered in the same batch as mine Alan (10345) on June 1st 1922.
It left the works on 20th Sept that year & was equipped with sprayers, half canopy & water lifter. Most likely a living van too.
No diff so it wouldn't make a very good tractor.
Best of luck with it :)
