Bronica ETRS Light Seals

I’m curious where all the light seals are on a Bronica ETRS. Body and film back. We have one coming and I would like to replace the light seals since I’ll be using a 220 film back with 220 film.

Thanks.

I believe that there are no visible 'seals' (foam), but merely designed-in light 'traps' (baffling) to block the direct path of light transmission thru connection points like back-to-body.

I have a few of them , and haven't noticed any , other than the ( as mentioned above ) light traps . Peter
