Maybe you can post some pictures of the tea?
I might have posted this a while back, but I got a few canisters of Golden Sail brand Tieguanyin a while back from a store here in LA. The canisters (especially the big one) are very heavy duty; I'm guessing they're maybe late 90s / early 00s, but don't know for sure. Even compared to the pewter canister Sea Dyke Tieguanyin, this (surprisingly, to me), is a fairly light fired tea, with medium oxidation.
Not bad, for what it is, and the price was worth it for the canisters alone.
Second photo kind of shows the somewhat unusual design of the double-lid of the big canister.
