Firstly the Vz.33 reworked pieces, i personally dont believe it was realised by HZA! It was realised mostly by police armorers for dress using, as Vz.33 have a short Mauser slot attachment this didnt work when You remove the barell ring, so its no a bayonet but only a Sidearm, not possible to use this in combat or bayonet fight.
Secondly there exist manuals for reworking Vz.24 bayonets and their using on rifles, but no manuals on reworking Vz.33 bayonets.
Thirdly Your bayonet is certainly a Vz.33 piece,with removed pommel, and new pommel added, the grips are made from mostly spare parts, but without drilling holes, as the small screws would be lost in large holes for original screws.
You should looks under grips.I believe when the tang is ok and not very refurbisched, You should found there a E lion 35 acceptance.
As mentioned before, there could be a possibility that germans removed by some of the Vz.33 the barrell rings and used its as dress sidearm, but certainly only in area of Protektorat.
Postwar all these pieces were most real send to Film Studios as not usable already for Army or any other branch in CSR.
Or You have a story from Vet, that he found it on a dead german SS body?
I believe these piece were not prior 1990 in USA, and were not found in any large old collection. I believe Mike Welser or other would write about this in early 80ies??
But maybe You will find other proofs?
