^^ those are nice bikes for working on and turn into very nice riding bikes as well. That looks like a very well preserved machine. Lucky the Brooks is still attached and good shape. Do you have a cotter press or large vice? Both are great for getting cutters out.

The handle bars look mint, great hoods and tape. I would try and keep those together.

Will look forward to some more pics while it goes through its transformation. The 3 speed Rando idea sounds great!
