Forget that one Perry, the laughing stock of optics, but if you can use it, who cares.
There were three models in all plus Hako made their own labelled one mid 94 to 95 same as the mark 1 Tasco the best of the lot but vary in build and optics greatly, same as any other asian rubbish.
Mark 2 deemed the worst of the lot with pink lenses.
The mark 3 as such was assembled elsewhere, the 40 and 50's are ok the 60mag rough but still better build than a BSA or Niko.
