Tin Toy Plane Production List Project

[Tone]

To All:

I have several small toy planes marked with the following trademark: a letter K inside a diamond with intersecting ends. When I looked around on the internet several months ago - such an arcane subject is not seen in toy books that are preoccupied with major manufacturers such as Maerklin, Schuco, Arnold, and Hubley - the best I could find was Ohta. Now I see, on the Dockerills web site, that this mark might stand for Koyo Kinzoku.

If anybody has a reference to positively identify this trademark, please let me know. Thanks.

Not a clue, Tony...I would have to ask you to ID it!
Can you post a picture of it, please?

I believe it is Koyo Kinzoku Co., Ltd. - The Dockerills website, as well as the book "T.P.S. Japanese Toys - Amusing Playthings from the Past" by William C. Gallagher, agree on that identification.

Thank you for that reference. Evidently, there is at least one book devoted to obscure, but prolific, toy makers. I have never seen that one, though.

Dockerill used to have the K-in-diamond trademark stand for Ohta, before he changed it, and that's where I got that information. I wasn't certain since the earlier Ohta mark was so different.

There is still a company named Koyo Kinzuko but it looks like an electronics components manufacturer.

The Gallagher book is pretty thorough with the manufacturers it mentions.

The Ohta logo is actually a KO, with the white K inside a solid black circle with a delineated white ring around the outside.

It stands for Ohta Kasaburo Co., Ltd. and is derived from Mr. Kasaburo Ohta, who presumably formed the company.
