Danish inspired?

I found two of these chairs at a small town antique store in NW Oklahoma. I removed two layers of fabric, and I believe the original fabric is shown in the second photo, and upholstery tacks were used instead of staples. There is stamped information on the bottom of the seat: NO. 1000 267 Green. There is also pencil writing with a date of January 1963 on bottom of seat. I have found a similar Danish design, but not exact. I think the green paint finish could be original. Six screws secure the cushion: four on bottom and two at back by spindles. I would love to know more about the origin, year, maker of this chair.
