I'll have to dig them out and see,the pic is about 8 years old and they have since gone into 'storage',but I know some of my 08's were unit marked.
The center one in this pic had the saw back removed and was reissued after the first world war.Also note that the top bayo has the high eared crossguard,as do all in the first pic,while the bottom two have low ears.I believe the high eared style was discontinued in 1916.
