There are a few notes about those L59 rifles, one of which you have. They';re quite unusual as opposed to rare but are a genuine official Lee Enfield. In fact, apart from the No8 rifle which is still in service, the L59 was the LAST true Lee Enfiield in Britishservice. Keep it because they ain't makin' any more. In fact, if it was me, I'd strip it and rebuild it properly (ask BDL
to do this.....) and give it a semi-pride of place in your little collection
