A Vintage Parker?

[berc]

So, I was going through my old stuff and I found an old fountain pen (as I luck would have it, I did not find what I was looking for). At first sight it didn't catch my eye as it looked like an ordinary generic pen. Also it didn't have any numbering or engravings on itself (even the nib and the body were "engraving-free"). However, I did not look the clip closely enough. There are these triangle like engravings (sorry, I do not know a better way of describing the Parker logo; maybe arrow like engravings?; anyway, you will see for yourself) that remind me of the Parker logo. It is a cartridge operated fountain pen. So, fellow fountainpen users, I would like to ask you for your wisdom, and help me in identifying this pen and telling me truth: whether this pen is a legitimate Parker?

Not a Parker to me.

To me it looks like a German School pen, not Parker. It looks like normal standard international cartridge the one on the side.

First of all, thank you for your replies! A bit disappointed, however the pen writes quite well, considering it is probably one of the cheapest you can find around.
Btw, the cartridge is made from TOZ (Tvornica Olovaka Zagreb - Pen Factory Zagreb), and yeah, it is a standard cartridge.
