On the ethics of restoration, I have been thinking a little more recently.
If you look at the photo below, a lot that came my way last week, you'll see there are bits and bobs that would normally get thrown out in any kura clean-up. Pieces of attached rag and wire look like junk. And that would be the end of their history.
Occasionally I will find a powder flask body that has lost its cap and/or other fittings.
Conversely in the photo you can see a necklace string with two caps, (one primer flask, one coarse powder flask) but missing flask bodies. There is an apostle 'hayago' tube with no cap, and the remains of a kurigata from a powder flask. Fairly useless on their own. What looks like a coin purse has a slit in the side for insertion/ removal of musketball. This at least should clean up a smidgen.
These things, made with design and purpose, need to be saved. If I can find a new life for any of them, I will.
