There is substantial variability with these marks since they apparently did not got struck in any consistent manner (possibly by each chamber before entering them into service - maybe only if deemed really needed); many VOC employees did bring their own weapons though.
Museums are well-known to have fakes and other non-genuine pieces in their collections. Like with any other collections, we'd have to carefully establish any single piece being legit before relying on it. I believe VOC marks on blades is a research topic that still needs to be addressed in detail.
BTW, most ethnographic pieces did not enter collections before the late 19th c. - way too late to exclude any "rework" of wannabe VOC blades...
I can't give any definitive opinion on this piece without examining it in person (and likely not even then). Just keep in mind that collecting VOC blades is considered quite a quagmire.
Pending further research regarding the VOC mark, the importance to me would lay in the period blade with proper mounts (except for the replaced grip). Those are rare to begin with...
