The "ONLY" Stanaback Specials that had or have numbers were leather handles. The 4" version was a traditional straight leather handle, red, white & blue spacers and was limited to 100. This was in the late 80's. The longer one (4 5/8") was also leather (still is: I have a handful left) but had all brass hardware (hilt, spacers and butt cap and a "commando-shaped" handle. There were /are going to be a total of 200 numbered.
