Louis Vuitton Gold Brass Lock and Key Set No. 230 on Sun Keychain.
Keychain is brand new, unbranded, gold tone Sun charm.
Lock and Key Set is authentic, vintage, preowned, showing normal signs of previous use - scratches, spots, dings - but it's still a gorgeous lock set despite these flaws. I have cleaned and polished it and will polish it again before it heads to its new owner.
