For older and/or discontinued Gerber models, I tentd to look into Ebay and buy a for-parts or damaged tool to scavenge. I'm not clear if you have a Multiplier or a Flik, so that I can assist.
Edit- I looked the number up, and its for the early type Multiplier, in black oxide; there are several examples in Ebay as of now (10 April, 1204 hrs in the Caribbean).
