Today we will talk about the oldest Prima ocarina in my collection, the Prima Cornetta M5C. Most of the following are from Kaori. She was introduced to me as a close friend of the Aketagawa family and a curator of the Aketagawa Ocarina & Art Museum, who also manages the Aketagawa Museum’s Facebook page: http://www016.upp.so-net.ne.jp/aketagawamuseum/index.html.
There are five total stamps/seals on this ocarina, two on the top and three below. The two on the top can be read easily: “Prima Cornetta” and “M5C” . According to Kaori, the letter “M” in “M5C” means “metamorphose”. No further information/explanation was provided to me as how “M5C” is different from a regular “5C” and I do not own a “5C” to compare side-by-side.
From this page: http://www016.upp.so-net.ne.jp/aketagawamuseum/goods.html and the image below (from the MT-8Bb), we can see that each model of Prima ocarina has a number, a key, and a name. They are:
1C “Piccolo” in C
2F “Cornettino” in F
3G “Larigho” in G
4F “Doubllette” in F
5C “Cornetta” in C
6Eb
8Bb
9G “Alto” in G
10F “Tenor” in F
12C “Bass” in C
14C “Doubllette” in C
It should be noted that the numbers seemed to be in the order that the key were introduced, and we are missing 7, 11, and 13.
For the stamps/seals below, at the rear end is the round seal with a ram sketch and letters “LEHL I.F.M.I.”. It is believed to be used on Prima ocarinas from early 1950s to around 1960, which is the second oldest Prima seal/stamp. “LEHL I.F.M.I.” stands for “LEHL (レル) Institute Folk Musical Instrument”, which was the name of the workshop that produced Prima ocarinas back then. According to this page: http://www016.upp.so-net.ne.jp/aketagawamuseum/about_ta.html, Mr. Takashi Aketagawa presided the workshop since 1950 and presumably until he passed away in 1958.
According to Kaori, the small black stamp on the body has the following words (from top to bottom): “ESTRO Terra Japonic OCARINA”. You may also see the same stamp more clearly on this ocarina.
A carving/stamp at the tip of the ocarina looks like “Cornetta”.
Update (8/13/2019): According to https://www.facebook.com/aketagawamuseum/posts/2329060543867466, the carving/stamp at the tip of the ocarina is “PAT.R.N.379907”.
This ocarina was bought from ebay on March 11, 2019, from seller “doki-dokijapan”. It was shipped from Japan and arrived on March 20, 2019.
