Purchased Type 99 recently.

Principal attraction of this particular gun is its completeness and relatively good condition.

As far as I can tell it's a series 1 Nagoya. So early production Type 99. Is that a correct assessment based on markings.

Metal has quite a bit of lite surface rust as though it spent a fair amount of time in the elements.

Complete with AA sites, monopod, cleaning rod, dustcover, sling and unground mum & bayonet. All matching except bolt.

Most screws are staked. Was this typical? Many screws I'm unable to remove. I think this is more a function of rust than staking. Any tricks on removing stubborn screws beyond penetrating oil?

The sling is rubberized canvas and stiff as a board except one spot that is thin and flexible. Is it possible to restore flexibility. Would anyone consider cutting off or is that sacrilege?
