In 1971 it was decided that the slipjoint contract would be move to Camillus Knife of New York and their designers used a exposed pivot pin on the bolsters which made blade repair and replacement easier. The Camillus version of the Buck slipjoint was straighter in form, had ends less rounded, gave the appearence of deep finger nic grooves and the first models had small flat scale rivets. The black sawcut scales with Bucks knife, bolt and hammer escutcheon continued.
A few Scharde made knives continued to be issued till the supply dried up later in 1971. As the transition to Camillus proceded additonal models were added. By the time full Camillus production was under way Buck was offering a 301,303,309 and 305 sized models.
Markings were similar and are represented by the 301s listed and pictured below.
Left to right:
1971, Scale rivets, Made in USA on tang, NO model number on tang, two versions - single brass scale liners and double brass liners on one side.
1971, Scale rivet, Made in USA on tang, MODEL number on reverse tang, one version - single brass scale liners
1971 - 1974, NO scale rivets, Made in USA on tang, MODEL number on revers tang, one version - single brass scale liner
1974 - 1985, No scale rivets, BUCK, 301,USA on front tang, nothing on reverse, two versions - single brass scale liners and two liners on one side.
Example of double brass liners under one scale on end. The use of extra scale liners is to 'fine tune' the 'crinking' or bend in the blade so they do not rub when folded into the blade well. (i.e. three blades, only two springs). As an example the last two knives on right show two odd-balls that issued during this era, Winchester contracted to have their name on escutcheon and because the 319 and 301 shared blades some mis-matches occurred. In this poor photo you can barely see 319 stamped in place of 301 on the tang. But sheepsfoot and spey blade in knife well, missing is leather punch to make it a real 319. The next knives in timeline after these begin actual Buck made models.
Camillus produced additional models and its relationship with Buck continued even up to the closing of factory in the mid 2000s. But Buck was making decisions which would set the course for the future.
Buck builds a slipjoint production line and begins to issue there own made models late in 1985. Buck takes over the production of the most popular models of their slipjoint knives, the 301,303,309 and 305. With the remaining models continued to be made by the Camillus factory.
Buck began by marking their knives with a date code stamp following the model number on the tang. They issued their new knives with improved 425m steel.

A new excutcheon plate replaced the traditional knife, bolt and hammer. The new plate simply said BUCK in capital letters. A few knives were produced in late 1985 and did not receive date code stamps, but these are rare. Between 1986 and 1988 these version of the four Buck models were heavily produced. This era was consistent and only the date code changes yearly over this period.
Represented here by photo of model 303s.
In 1989 after continued outcries over the escutcheon change from the knife, bolt and hammer Buck went back to the historic symbol. The newer BUCK escutcheon was also prone to have the ink quickly rub off leaving only a shallow indention of BUCK.
In late 1989 Buck designers were busy fine tuning the four models they produced. For the 1990 issue, blade steel was changed to 420HC, the knife,bolt and hammer settled in as the escutcheon plate of choice and the 303 was made with three stainless steel springs, one for each blade. Other changes were on the way in the near future. Here is the historical line-up of the 303, starting top left down and then top right down. 1966 - 1990.
After 1989 things get complicated with issues of special scale material, blade markings and changes in materials to all stainless steel occurr. That history will be written in the future.....you forumites can at least appreciate that I now am in trouble with BCCI as this posting could have been written as a newsletter article.....and may yet be.....good luck on you IDs.
