Hi Ralph,
I think you have EXACTLY the right outlook on old tools, and there's absolutely no reason for anyone to have to justify the motivation, nature, or content of their "collections" here. As far as I know, there's no right or wrong way to enjoy antique tools. It's the simple love of old tools, in this case hand planes, in any condition, that will hopefully keep the discussion going in a positive direction. I've never really heard the term "paint collector" either, until very recently. I can't say that I necessarily agree with its use nor the seemingly negative light that it casts on a certain segment of those who also enjoy old tools, but again, everyone is entitled to his/her opinion.
I think your work is amazing and your grandchildren will treasure your creations for all time. I'd also hang onto your grandfather's #45. Whether you ever use it or not, doesn't matter. Its sentimental value and direct connection to your past is priceless. I still contend that it's nice to see old tools as they looked brand new. From an academic perspective, they're wonderful to study in that condition. Still, as old as they may be, they all lack the decades of character that only honest use can bring to them. You have it right..... You're interested in old hand planes and tools for your own reasons. I'm a fan of your work and I'll keep watching.
