Hello. I am a new member of the Site. I was given an underlever .22 rifle which has absolutely no markings on it whatsoever. From images online I think I have narrowed it down to an SMK XS36 but an earlier one (I think). Either way, it wasn't working properly so, having disassembled it, there are two problems. One is that the spring guide (cheap plastic thing) had perished and bits of it were caught in the spring. So Sports Marketing are sending one of those. I just hope I have got the make and model right. The other problem is that the trigger mechanism is in bits. Does anyone have or know where I can find a diagram for the rifle? Sports Marketing say they don't publish one to owners for safety reasons. Any help would be gratefully received. Thanks. David
