トランペットの製造時期と勘違いしてませんか？書いてあるシリアル番号だとすると製造時期は１９６５年頃になりますが。

Translation / English

Regards the manufacture's serial number, it says 1945 but isn't this around 1960?
You might be mistaken this for as manufacture's date of the trumpet ?
According to the serial no. written, it should be 1965.

Translation / English

I am asking about the fabrication time of the item. You said about 1945, but I suppose the 1960s. Don't you mixed up with the time for your trumpet? I think the serial number of the item tells the fabrication time around 1965.

Translation / English

In regards to the manufacture date, you have 1945 written, but isn't it from the 1960s? Is it possible you are confusing it with the trumpet's manufacture date? Going from the serial number you have written down, the manufacture date would be 1965.
