That pattern came out @ '93. As to when the guns were dipped in it I dont know. Its possible they could have even been dipped several years after with left over stock film. That pattern was used for dipping for a couple years, Trebark was first in 92, then bottomland original (like yours) then came greenleaf in 94. You can get in touch with gun manufacturer with serial number to see when the gun was made. I'd guess real soon after manufactured date. Those were sold new with the camo.
