I agree with Mike, only the Type 99 had the A/C sights.
A original unrestored Arisake can go for north of 1K if in very nice condition with a intact Mum. The Arsenal and Series well make a difference in value.
Very few still have the original Urushi finish on wood as most GI's refinshed these on the way home aboard ship. Urushi is derived from the Sumac tree and is poisonous. There are many documented cases of men aboard ship returning from the wars end devolving skin rash and respiratory problems. Caused by GI's sanding on captured Jap rifles. Aboard ship this fine dust would be spread be the ventilation system and effect the entire crew.
A type 99 in good condition with original finish intact, removed Mum, is a $300-400 rifle. If it retains the Mum it can be double that.
This Nagoya Arsenal series five with Mid-War Type 30 bayonet has a mismatched bolt and is missing the Mum. It does retain the Urushi finish and has about 70% of the blue finish remaining. The chrome bore is very nice. Original A/C sights with reproduction sling, muzzle cover and mono-pod.
