Register a car in the UK. But what if my papers get lost?

[Rawsox]

Got an E30 I want to register in the UK. It's from Sweden. Got the original papers with the car and there's no tax to pay on import fees.
I know I need an MOT and insurance to register the car (MOT and insurance on the VIN) and £55 for tax registration.
Only concern I have is if my papers get lost at the DVLA! I've only got the one copy (original registration document)
They won't take photocopies.
Anyone else had that worry in their head?! And how did they get on with it?!
Or shall I just send them. I would send them recorded signed for etc etc it's just the DVLA misplacing them that concerns me!

I would photocopy them anyway, peace of mind is key

Make it a good photocopy with a bit of teabag-aging for good measure..

I’m pretty sure (and happy to be corrected) that the DVLA won’t return your originals back anyway, so I’d be looking at what other documents they might accept first, just in case. Isn’t there some rigmarole that they’d accept some alternative manufacturer proof?
