Mitchell spool identification

[mattus]

Was googling for some Mitchell spool sizes and didn't see an easy list. I am new to Mitchell, I just picked up a 302 salt and 300 that I tore down and rebuilt, but in the bottom of a toolbox I got with it was two really large extra spools. Not marked Mitchell but I assume they are, the only markings are on the bottom that say "T1 France" and "T3 France," as well as a "use garcia bonnyl line" sticker.

Below is a link to photos, top of reel is 3 1/8" and bottom is 3 1/4". I was going to guess these are a 498/499 sport fish reel? Can anyone identify, I'd like to maybe find one of the reels online to buy if its not a super rare one.
