A bit of a revelation in the '80s, cheap, lots of plastic but Japanese plastic so solid compared to Crossman build quality of the same era.
Seen as devastatingly accurate, but compared to the competition in the budget range - Meteors for example - recoilless nature was mind blowing no idea how they'd stack up against modern equals.

Lets say the chances of an airgun being seized and run over a chrono were slim back then, and long range shots were a forte compared to their peers for the youth lucky enough to have one of these as his Christmas present.

Versatility was also excellent compared to its peers - 2 strokes for popping dandelions in the garden was much easier than pumping to hunting power.

Owned a jazzed up venom version, which was short, compact and handled well, but all that pumping relegated it to nominal use once PCP's were cheap and easy to refill, final nail was multishots - you could rattle off 10 or 14 shots from a PCP before you'd pumped enough air for the second shot in the Innova.

I'm sentimental about them, and handled with interest a Webley Raider (?) the rebadged relaunched version in a shop a couple of years ago. Certainly the Ace was on my wish list as a teenager before HW's took over the world

As I understand they've been in production under one name or another (various far eastern clones have been known of through the 90s and the 00's after the originals ceased being imported), they must be pretty much bullet proof, easy to maintain with non complex spares sourcing parts can't be OTT- the AK of pump ups ?
