Depending on the price, and if you have the money to spend, I would consider picking it up.
I am not quite the "purist" that some are here, totally uninterested unless it meets a very high expectation. That is mostly dictated by my pocket book.
I have never seen a Geco 33 rifle in any form, in my life, and so I would be inclined to pick it up. Should you see another in the future, you can always sell this one.
Check out the thread I made on the Walther Meisterbuchse I purchased. Absolutely horrible. Only one I have ever seen in the flesh. Should I ever find another, and it is in better condition, I will upgrade.

I had fun picking that one up just to for a representative example. Shoots well, let me examine an action/mechanism I had yet to get my hands into. Best part is, I don't worry about taking it out to shoot like I would any of my really nice "collectible" guns.
