Are the phrases.

「Purveyor to the Imperial Household, and the Department of the Army and the Navy.」
I believe this is the meaning of the phrase above however, it is no longer used at he Department of the Army and the Navy.

What kind of the phrase should I use if I want to use the past tense for「陸軍と海軍」part.?

尚、空軍は英文中には存在しないので、Army（陸軍）をそのまま使用しました。
