How rare are ZB 39 ("commercial" Bren LMG) magazines in Canada?

[AlexV]

So in a batch of Bren LMG magazines I got a ZB 39 magazine. At first I thought it was an early design magazine but found out it's a ZB 39. I want to sell the mag (pinned to 1 round unfortunately) and was wondering if it's worth more than a Bren LMG mag?

You may be able to get around $100 for it

are you sure its not a 8mm bren mag ? Inglis made thousands for export to China WWII.

Yes, it's only marking is a circled HK stamp. It looks like a Bren mag (and it works in a Bren) but when you look closely it's quite different.

Go on g*np*st and compare what you got to what's posted. There are quite a few bren mags up on there.
