Just bought a lovely air arms sm100 .177 in mint condition.
I know it's a mk 1 because it has a silver coloured breech block and muzzle. However it has me confused; it has a walnut thumbhole stock with adjustable butt pad.
To the best of my knowledge the sm100 came with a beech sporter stock whereas it was the xm100 came with a walnut stock.
So which have I bought; any ideas.
