As far as I know Will they aren't. These were a surprise to JBF themselves. Bill Howard actually emailed JBF and told them
"We recently ran some #92 pattern knives.
While doing so I cleaned out the #92 designated cabinet in assembly to
put together any leftover inventory of previous #92 runs.
I had quite a few parts for the JBF Champlin knife we previously made
for you and I put them together and finished them also.
Here is what I made in JBF.
15pcs. 2bld with East India Rosewood handles.
1pc. 1bld. Spear East India Rosewood handle.
1pc. 2bld. Original Rosewood handle provided by you.
All with correct shield but no blade engraving.
..."
Sharp little buggers

Only the 15 2blade were sold to the public.
Not sure why they didn't just use the Catt rosewood that were an included though, perhaps to save the production totals.
A "old" new knife.
