Never owned one.
Always thought they were an elegant rifle. Quirky and tricky so definitely for the collector rather than for the shooter.
No one is ever going to make one again. They are from a particularly difficult period of air rifle trading, so like quite a few at that time numbers are low so rarity will be strong. There are quite a few in this quirky arena and what happens in their place in the collectors market is anyone's guess. Eventually they should do well, but how well is another matter. Depend on the strength of the air rifle collectors market. I suspect in the future that could be quite strong as they are good items to collect. They are at least "interesting".
