Could anyone help with a date and a model for an old rifle serial no L21637, it is in .177 and in reasonable state. It does shoot and the tap smooth and tight.
I know without pics a value is difficult, there is no etching visible on the cylinder, the butt stock is in good condition and the wood plug looks to be original, screw heads have not been mullered either. Sights look to be complete too

any info appreciated
