That looks to be a nice looking pen and I would say that you got it at a good price, especially as it comes with the metal holder. I think that its very possible that the over-under feeda might have been discontinued by the time yours was made. Take a look at this example that Richard posted about a while back, and his comments on ink flow are well worth noting.
BTW, they've stored the pen upside down in the holder ... if you think that the holder would clip onto a shirt / jacket pocket then you can see that this is wrong.
Although we can't see the nib detail, it should have a nice bit of flex to it. Enjoy it when it arrives.
