it is somewhat sturdy, but i personally wouldn’t trust it to hold a harp, i’ve been calling local music shops and museums and they have told me it may be from around the 1850s, but they could be wrong. The only other one i have been able to find online is someone selling just the front door of the case on ebay for $1500 as a conversation piece, so i feel it would probably be worth it to restore it. but other than the one picture of it i can find on google i can’t find any real information about the case
