1999 Super Match I

I recently purchased a 1999 Super Match I. I'm pretty sure I paid less than it is worth but I wanted an opinion from someone familiar with these. I would like to say it is stock but it is not. It has a 4" BarSto barrel and a "Thoroughbred" slide. I'm pretty sure the barrel and slide were done here in Gilbert AZ. I heard he passed away but unable to find anything. I will say it shoots like a champ and extremely accurate. I know the gun was made in March of 99 and was probably one of the last real customs Kimber put out before they expanded in to what they do now. I guess I just want to confirm the price I paid was a good deal.
