Doublegun smiths are a bit thin on the ground in the state of Washington. Which makes it a great place for the DIYer. (Sorry, I only do my own) However, if you don't like to do your own work: Randy 'the stockman' Osbourne at Osbourne and sons does nice work. He doesn't do doubles exclusively, but he does like doubles and has some spare bits for Elsie's, etc. He's in Onalaska and his number is 360 978 4781. Mark Larson is in Tacoma. If you are on the east side Dennis Earl Smith in Thye Valley is well known for expert stock work. A little further down 97 in Bend is Cody Kearcher for stock work, and general repairs. Hopefully one of these gentleman can help you out.
