Like a mutt…. a rebuilt typewriter can come from many parents. Like a dog from the pound the mutt may have many advantages over the pure-breed. I look at my rebuilt Woodstock and know it has had a long and productive life and been used a great deal. My old Woodstock may have been repaired or well taken care of… but for the most part retains its “as bought” function and appearance. After 96 years does it matter.
In the long run it does not.
