Lovely, good looking guns, the Cadet and Cadet Major. I have several, and love them to bits. The Cadet major had a longer compression cylinder and adjustable sights and trigger, The smaller cadet was aimed at youngsters, as a first gun. They did make a quantity of guns with spliced, three piece stocks, similar to the larger Airsporter range, however these are not common. Earlier guns, can suffer from the crossgrain strengthening fillets in the pistolgrip, working loose. Not sure what the fix is for that. I have also come across guns cracked across the pistol grip, so clearly this was an area of weakness on these guns.
Good condition guns with the photo etching intact and increasing in price (I have always thought, the guns were worth more than the average selling prices they received) and now they are coming back into popularity as more and more shooters realise what good fun they are to shoot.
Never again will we see that quality of materials used in a junior air rifle. Like people have said...... Bombproof design.
Enjoy
