Note - The illustration #23 shows the old style one piece type carrier extension, which has been replaced by the newer model 82, 2 piece extension arms.  When replacing the older unit it entails replacing #3351, #3352 & # CES spacer 

The Centurion II model used a different Slide Assembly, that we can not easily duplicate.  The model 82 used another version, but different yet.  The rear attachment to the carriers are different, therefore requiring a different carrier than the Centurion.  However we have come up with a Conversion Carrier that will allow you to retro-fit our Centurion Slide Assembly into these later firearms.

WEATHERBY CENTURION ACTION SLIDE BARS—It has been noticed that the notches cut out on the bars (normally .500) on a few guns is a longer dimension  .555+-.  Known guns with the longer notches are s/n NA0094X, and another s/n NA0268X.  One customer who has one of these low numbered guns & it is still unfired in the box, says it does not have a model on the end of the box, just “automatic”.  These s/n would have put them as transition Centurions make by Nikko, while they were also being made by KTG, during 1973.   It is not known when the change may have been made to the later common .500 dimensions.

Also on these early guns the slide bars were radiused on the rear.  The Patrician used a LH slide bar that was angled off on the rear to act as a slide stop.  This necessitated the need for 2 different bars in production.  Later they simply used the Patrician bars on both the guns. However the first Centurions with the wider notch apparently needed the shorter radiused LH bar end.

WEATHERBY CENTURION - Intermediate Centurions, as with s/n A04905, used the newer carrier machined for the (2) stamped extensions with a carrier extension that used two of the later single type ones.  But they had a rivet at the rear holding the two extensions together.  This configuration appears to be an intermediate version between the old one piece cast extension but fitted to the new carrier that had a machined spacer section to separate the extensions.  However the way the riveted extensions are made, they could have been an early retrofit for the cast extensions IF a spacer was also used at the front.

This gun also used a spacer of .233 front to back thickness & 1.157 dia. on the magazine tube, against the receiver's front.  It appears this spacer acted as a dual stop, abutting against the rear of the slide assembly tube & the front of the receiver.  This was timed so that the action bars are stopped at the same time the rear of the carrier hits the inside rear of the receiver.  The forearm had a thin dual thickness C shaped metal liner of .500" glued into the rear of the wood.  The dual thickness involved the thinner part to blend in with the forearm's inner hole & the rear thickness had a close fit over the above mentioned spacer.

The slide tube also has (3) equally spaced holes of .203 dia., back .600 center line from the front of the tube.  This apparently acts as an initial gas bleed off.  The slide arms have only (1) set of alignments pin at the silver solder joint to the dog-bone.  

The gas piston has no writing on it.  The gas tube has a .065 dia. x .750 long retainer pin 1.535" in front of the tube's base that screws into the magazine tube.  This pin keeps the gas piston from falling off during disassembly.  The hole for this pin is in line with the (2) gas port holes.

The ejector is slightly different in that it's tail was shorter by .200 & it does not have longitudinal grooves of the #3205.  

We have come up with a conversion off a different brand firearm, that was made by the same Japanese manufacturer where we can supply a lifter conversion.

We also have in our projected new items, to start making the #3227 Disconnector before long.

Operating Handle #3245
