Thanks for the replies, I can definitely learn something from each of them. It seems like wood figure comes up a lot and that definitely narrows the field, there also seems to be quite a few of these that are middle of the road wood, still real nice looking but lack that pop that the highly figured walnut has. I always have collected for personal satisfaction but try to keep it in perspective that it is also an investment. I've been impressed with the condition of all models of No.1's that I've seen, they seem to be well taken care of for the most part and high condition rifles are available.
I do have one No.1 B in 25-06 that is a second year 133 prefix and a solid 99% rifle. Not a super early gun but still a very nice one. I had it out last week looking it over and couldn't believe I only have one model No.1. As Trapperon mentioned, I thought the same thing about the 1-H, fewer calibers and it should be a good place to start and keep focused. Plus the big bores are something that interests me.
