As WTF says, that is a Siamese SMLE, it is probably the original wood, however it has been sporterised, wood cut short and the barrel shortened and fitted with a sporting front sight.

It should look more like this Australian one...

As it stands, it has little or no value to a collector. With the correctly marked wood and metalwork then you have something people would become interested in.
