In this case, I understand that this is not a family sword connected in any sentimental way to the poster or any known persons.
I might repeat my view of cleaning efforts:
- Collectors often say they value untouched, intact items.
- Grooms often say they value untouched maiden brides.
- Once a collector gets control, he just can't resist messing with it.
- Once a groom gets control, he just can't resist....well, you know.
One result in both instances is that NEVER AGAIN is the coveted object untouched, ever again, it is changed for all time.
So, it is wise to think carefully before starting.
