Vintage kids bike (Shurdington GL51)

Bought by me many years ago, dismantled, repainted and re-built. Must be at least 40 years old. Known in our family as the Magic Bike as, due to its low centre of gravity, it has successfully launched children and now grandchildren on to two wheels. I put in new inner tubes but now the covers are degrading. I bought new ones but don't have the time to fit, so you can have these as well. Needs the saddle replaced or re-covered. A good project for someone.
