I know the present owner ( seller ) of that bike. I restored the saddle for him and made the straps for his ''Persons'' tool pouch about three or so years back as I remember. The pouch was an unusual mahogany shade of color and I was able to match the saddle and strap leather to match it. I also know the person that the present seller bought the bike from, I think about four or five years ago. He has had this bike up for sale for some time now. Not a perfect G519, but not bad either.
Regards,
Bill
