It looks fine. If you do a very good job it will be just as valuable if not more. A rewired and top condition 15-91 or 201-2 is not that common. If you go for black paint and decals like the original there's always some who prefers that, and there are quite a bit of interst in alternative colors too. Very few of us do this for the machine value. After cleaning and fixiup a machine can often be sold at a higher price, but these machines are worth most to those who use it and appreciate it. At least they keep their value.
