If you check the examples at the link I gave you can see that those are all very small !! Largest I believe was only 15 inches tall !! Today we have jewelry chests that are larger than them !!
Are you planning to sell this chest ?? If so,, I would leave it as-is !! Buyers of this sort of chest want them original !! Repairs or restorations,, unless you really know how,, can reduce any value by 50 to 80% !! And remember,, I can only date this chest by what I can see,, it could be older than my estimate !!
