Len:

About 20 years ago, at least one importer was selling like new S84/98 T3 wood grips. I bought s few pairs but ultimately had reservations about them being of WW2 German manufacture. All were devoid of any markings, etc. They seemed to fit on some bayonets but were a problem on others (fact being all grips require a degree of hand-fitting, that was not a surprise). The grips also seemed to be kind of slabby and not cut deep enough to easily accommodate the ridge on the sides of the flashguard. Could well have been post-WW2 mfg for replacement...possibly Spanish? May have seen a pair or two like you show never cut for screwbolts, too.
