I removed the bolt and the number appears to be PF 262914. I just wonder if this bolt was properly fitted when someone used it to replace the original bolt.
If it was properly FITTED, then the numbers would have been scrubbed and the 'matching' number added to show that the bolt now 'belonged' to that body.
Mine are not the best, but they are not too bad. I can think of lots of Enfields I'd rather have but instead of constantly striving for more, sometimes it's good to be satisfied with what one has...
