Hrm...
If you had to check eligibility with Zooma, then I reckon it's not spring or SSP. Because you would have known those are OK... so it's a multi pump!
And as you can actually shoot a group with it -- It's a Sharp Ace or Innova!
Unless it's a Benjamin or something. But I doubt it because aren't they usually .20 cal?
Do I win a prize?
P.S. Whoops, sorry -- I mean't 'Upper Rustington'
P.P.S. I think I once had a Super Meteor with the peep sight!
