Here are some photos of the rocket pistol. The Rocket does go back and forth. It's a pretty scarce gun. Related to the rifle.

It is complicated. It's very hard to predict future values especially with space guns, It's a very narrow market with not that many collectors. All it takes is a couple of new collectors with money to spend and the prices go up (remember Alan aka Solar ray) and visa versa. Face it; a lot has to do with spending power. If there are collectors with $ they will compete for the rare stuff and pay up for it. The rest of us have to work harder to find good deals and all of us have had our moments!
Ok here is the bottom line. I know 3 collectors (off hand) that would pay in that price range for this item. If at least 2 of the 3 collectors are bidding on it then more than likely it will reach that range.
Between 4000.-6000. would not surprise me (depending on who's bidding of course). I have only heard of two boxed ones and 2 or 3 loose ones so it's definitely rare enough to command a lot of money. Much harder to find than the Pyro pistol.
Here is an interesting item I picked up recently. A knock-off of the Coma Spaziale with some minor differences here and there. Very fragile hard plastic. Definitely not the quality of the Coma plastic and a terrible glue job but a cool variation none the less and surely a rarity. Is anyone familiar with the maker? I think it was made in Spain????
Here is the Dan Dare die cast version of the Atomic Jet along with the plastic version and box. The die cast version came first (hence the art work on the box) and was later replaced by the plastic version.
