I have a pair of front seats and a back seat that were from a early 60's 122. i dont know if the 544 or 44 used them but I think they had similar front seats with the low backs and not the textured cloth.

The set of 3 seats would be best suited to an original early version 122 4 door. a 62 to 64 122 would have this early style.

I think the seats changed prior to 66 to a style with a bumpy sort of vinyl, Headrests became a bit later, maybe 67 - 69 or so.

these might be a good candidate for someone doing a complete restoration of a 122 or possibly a 544 / 444 or duett with attention to originality. If you are willing to accept seats from some other car that will be a cheaper option. I paid $1,000 a long time ago to have my original seats repaired professionally with some sections replaced. mine have the headrests which are a bit later.

2 door 122s had a different shape to the back seat, mine is a 4 door so they are rounded at the ends and these reupholstered ones that I have are like that. the 544 / 444 likely have a different shaped back seat , but I'm less familiar with them.

im not sure what body color came with light grey upholstery. maybe a red car or red with white. easy to die them darker.
