Surpmil & Brian,

Thanks very much for your responses. So there’s definitely Suncorite 259 or some other kind of baked-on finish on the unpolished exposed surfaces of each of the Lee-Enfield No. 5 MK 1 rifle backsights. Now, can you tell me anything about the stamped “P” – which appears in four (4) different places on each of those backsights – and the stamped “46” – which appears in two (2) different places on each of those backsights?

Thanks in advance for any additional information you – or anyone else – can give me!!
