Scale pins on 112's - 2 & 3 brass pins

[chickentrax]

While re-blading and re-scaling a slabsided 112, that came with 3-pin scales [3 brass scale pins + 1 steel rockerbar pin], the liners were drilled for the 2-pin scales also...not countersunk, like the other 3 scale pin holes were, but they are there nonetheless...

I thought this odd...why drill both patterns on the liner???

The only reason I could think of was to use up existing stocks of 2-pin scales...if you had a big stock of them piled up...

If you have an early slab-sided 112 [say, a .112. ], you can shine a light in and see the extra pin holes in the liner...

Any other ideas/comments??? Anyone see any of the early slab-sided 3-pin 110's with dual scale-pin holes???

Edit: Just answered my own question...a slab-sided 3-pin .110. has the extra pin holes for the 2-pin scales also...

Trax,
I just spent the last five minutes staring into the interior of a late version two-dot 110 with three brass pins. The only scale pin holes I saw were the ones for the pins actually in use. Sorry, I was really hoping to see an extra set on holes.

Mike - I'm willing to bet it's only the *early* 112's [slab-sided] that would have the 2-pin holes...same as the 110's...Mine just happen to be .112. and .110. knives...Lessee...That'd be 1974 to 1980...

There must have been a transition year where Buck tried to use up all their old stock before switching over...Maybe the 110 datasheet has something on it...

Hmmmm...According to Matheny, in 1974, you could conceivably find a 110 with 2-pins, 3-pins, or 4-pins in the scales (not counting the steel rockerbar pin)...

So I guess 1974 is the transition year...and the blade would be a no-dot or a 2-dot [.112. or .112. ] ...

I know you gots some of them old ones...

Trax,
I looked at the two-dot 110 since that is the model that offers both variations. The earlier two-dots had two brass pins and the later variation had three. It may be that the first of the later variation 110's with three brass pins were actually re-worked liners that had originally been manufactured for the earlier two pin variation and then once they were used up they began making the liners from scratch in the three pin configuration. But then again, what do I know?
