Yes it does, very faint under the paint. So the serial on stamped on wrist socket and looks like electropencilled on side wall.Posted a picture below and the bolt.
I got lucky with it, not many people seem interested in enfields here.
I keep a sheet on each of my rifles, marking etc. Here is the info on this rifle so far. Please feel free to correct me.
