weird corny posts

one of the cornys i own has some odd posts and some other oddities.

the posts are deeper inside than normal ones, so they require an additional white plastic washer that sits inside the post. the ones in there look pretty fried, has anyone else seen these and if so, where can you get new ones?

it also had a pretty jankey red plastic gas stem, which stuck me as odd. the lid washer had squared edges, not the rounded ones i've seen on other cornys. and the lid is more rectangular than ovular like the normal ones.

still says cornelius co. on it and firestone somewhere on it too... i'm pressure testing it now, the guys i bought it from say it was pressure tested, but i reckon i should double check.

anyway, if anyone's seen another oddball like this one, let me know where you got parts, or if you swapped the posts or what...

thanks.
