105 mm wide Kindermann reels, tank to fit?

[Kevin Caulfield]

I bought these two reels for a steal some years ago but haven't been able to find a tank to fit them. Any ideas? They are 105mm in diameter. Can't post image as the file is too large.

Could these be 220 reels for the larger Nikor 4x5 tank?

The box says they are for 120/220. I actually found a one reel Kindermann tank including a reel on an internet website not too far from me.
