John, you are lucky to have the Senior model as only about 40 were made. They stopped making them as they were too expensive to produce. At the time they were several times more expensive than a Number 1 (current price for a new number 1 is around 11,500). I have a friend who had a pair of Seniors in perfect condition which he sold for 14,000. Heaven knows what they would have cost new. A bargain but out of my league. I do like AyA's and have four. Never owned an Arrieta but would snap one up if I found one I liked at the right price. Lagopus.....
