@pidgeonpost I'm aware of a number of similar incidents where the firearms have ended up being deactivated when they weren't meant to - absolutely gutting for the owner. Have you seen the asking price for some deactivated firearms now with the full certification? Absolutely amazing and occasionally more than an activated piece.
Regarding your Lee Enfield, I owned a number of them over the years and they were a pleasure to shoot although I didn't own any of the US/Canadian, etc. models. As a service rifle, they are of course one of the true icons and were very much 'recycled' when they became damaged back through the factories so they can live another day, albeit, the replacement wood they sometimes came back with looked odd if you were prone to a bit of OCD...
The one I had a love/hate relationship with was a No5 Jungle Carbine which was an utter beast to shoot given the shorter barrel and its lesser accuracy for that reason. When I first got it I used it for a couple of hours over 100 yards and in the morning was wimpering with the genuine pain in my shoulder - I should have known better given it had a steel butt plate. If anything it heightened my admiration for the lads that used them during times of service.
The K98 was also a superb rifle and as you'd expect, very well put together and slick to shoot, dare I say it, probably smoother than the Enfield.
