I saw the thread this morning but didn't get to reply until now. Looks like it's mostly been said. Rare sticker as noted in F&G. These are attached to low quality saya, black painted with crudely cast fitting. The sword blade and the quality of the accompanying fittings are of a similar nature. Have a look at the sword in this thread and my own example.http://www.militaria...saipan-oddball/
Both are incredibly poor examples of workmanship, cast badly and the blades are unsigned, painted with some sort of kanji. You can see on the close up of the saya Fletcher posted that the hanging ring is really rough. His is missing a few bits like the saya throat and has a slightly different tsuba but is materially the same pattern.
I would class these as rare (complete examples with the original sword) as I've seen very few of them and most are in pretty shocking condition. Bearing in mind parts get mixed up, these saya should always accompany a sword of similar craftsmanship.
As to whether these are late war or the serious poor man's gunto... I'm not certain, but the materials used suggest late war to me. Dawson actually has a police tachi that is nearly an exact match to these swords, except for the police emblem. I saw one on ebay but wasn't in a position to bid. It was a fantastic example of an incredibly rare sword. Sigh.
Anyway, enough prattle, hopefully I've not repeated covered ground.
