Interesting CZ VZ35 Sporter with carved stock

[45flint]

Just acquired this as I have been looking for a CZ VZ35 for a while. Was looking for a military trainer but this Sporter turned up and I couldn’t resist. Have no background on the piece and I am not totally sure what to make of it. No Sporter I’ve seen has such a stock so I have to assume a custom build? It’s in amazing shape so I really doubt it’s a military rework? The detail in the carving and the quality of the walnut is quite nice. It seems period as the Oak Leaf motif seems very German and Germany at the time of this high serial number has probably taken over the country. The stock is fitted perfectly with factory precision, and seems to me it gives the impression of being a similar age? (1939?). It does have the shorter cocking bolt which improves the looks but sure doesn’t help your leverage. I have seen a few others with this bolt length. You fellows seem to be the most knowledgeable on the net, curious what your thoughts are?
