Randall occasionally pinned a butt if the threaded tang was damaged or too short to fit a nut. Capt. is correct that it was common for Tom L. to pin butts, particularly on smaller knives. I have had several. Capt. is also correct than many of these knives were not marked by Tom.

As for spacers, LB's were no different than any other standard model. For those looking:

Valueman has an interesting example of Randall culture. I am in hopes that he posts his photos of the knife over here. The grind (amongst other things) shows some interesting qualifications, making it a possible hybrid or a shop experiment.
Let's see, Capt. Chris

Thanks Capt,
In responce to Peters request for a photo of my #11

Peter,
There are some additional notches along the top of the blade.
I've shown it to a few people, and it's not clear if it was done at the shop or afterwards, just the same, it's a oldie but a goodie!!
Included here is a shot of my user, I keep it clean. Also, as I was looking at them both, I noticed quite a difference in the grind of the newer blade, and thought it to be interesting enough to show side by side.
Can someone speak up on the changing grinds of this model...
:-)Rocky

that piece was floating around for years.

Never mind then

Rocky...and Crutch:
As I look at that blade and try and picture what it may have been (originally) it looks (more and more) like a #12-8", Bear Bowie.
Any thoughts?
Capt. Chris

This's stuff for experts...only!
My 2c

Given the positioning of the logo stamp, I doubt it was a 12-6.

Mitchell,
I didn't think it was a #12-6...rather a #12-8. Look at the large flat blade surface, along with the bottom (choil) configuration. Picture a #12-8 "Big Bear" cut down and I think the planets align. Of course, we'll never know for sure but it's interesting to speculate.
Capt. Chris

I tried to do the comparison, Captain, but couldn't quite make the blade outline fit a 12-8.
