The MK2 kit came is a cardboard box sectioned .....which included one section for the scope in the box that is on the E#ay post. The MK 2 did include the scope in the kit. However, the scope is not metal it was/is made of Polystyrene ( Plastic) like an Airfix model kit. It did/does have glass lenses.
As you state; the dovetails , 4 x grooved approx 15 mm, makes the scope fairly unique.
I would not pay any more than £40 for such a scope...
As some of you have stated the scope is the original one for the MK2 Airsporter and it does appear on the sales brochure for the MK2 Airsporter with a little 'write up'.
I have the brochure from 1960 and it's on it....
Just a thought....
Some people pay £40-£50 for empty pellet tins
I think that E#ay is fantastic....I have managed to source numerous parts for my 1983 Cagiva motorcycle utilising E#ay in Italy, Germany and the USA...
