15" Maltese Cross
This is the same 15" Maltese Cross pictured in  - http://www.slojoe.com/mine111.html
It has been completely reworked.  The Rear Bolsters have changed.  The Scales are thinner
and rounded.  The Brass Liners have been reversed.  The Front Bolsters have been thinned.  
It was taken from a matte finish to a polished finish.  The Button Release mechanism has
been reworked to change from a hair release to a strong lockup and release.
