Help finding an old Gerber model

[mserr]

My dad has had the same gerber knife for the past 20 years. One of the original LST models, but they don't seem to make this particular model anymore. It's about an inch and a half long and at the time was a model "200" there was also a slightly larger model maybe about 2" long called the "300". Now all that Gerber makes is the LST which is way larger than both of the old models, and the ultralight LST which I havnt seen so I don't know how big it is in relation to the model 200/300. Does anybody know of any knife suppliers that have the old stock of the older LST models? He doesn't like a large knife, so I want to try to get him the exact one he has. If anybody could chime in, I'd appreciate it.
