This is a North 760008A respirator with 42 pair of cartridges and 2 packs of pre filters. These are unused but they have been in storage for probably 20 years. The rubber on the respirator is still soft and the filters have been sealed, I cant find an expiration date on them. I know they're old, I would use them if I needed them, but you have to make that call for yourself.
I cant find a size on the respirator, it may be a one size fits all.

Thanks for looking.
