REMARKS:
===================================================================
MODEL »B1« is made by RICOH / Japan.  It is the ONLY WOODEN SR SOLD
by PICKETT.  It came in a black leather case,  which can be clipped
on the user's belt - typical for the  USA:  As seen in the "Western
Movies" ready for a "quick draw".
