chambers, do carry 97 stocks as spares
but neither their web site or printed catalogue states whether both mk 1 and 11 are avialable
the green stock may be difficult to find as a spare as this was a limited edition version .
but as always a phone around may provide a suprise.
hope you find what your after.
p.s another good place for weihrauch spares is guns international
in barnsley they have a regular ad in agw.
