SMK - Sportsmarketing G1015 .177

Hello, here we have an old Smk 177 air rifle,model 15,but that is the only information that I have. Pretty good condition for age, and seems to work fine, and surprisingly powerful. I do not know anything about this gun, it's just surplus to requirements. The telescopic sight is quite old & basic,Bentley 4x32, with signs of wear and tear, but quite usable, the rear sight seems to be missing. Ideal starter gun for plinking in the garden. Please study the photos as they do form part of the description. Thank you.
