25 Executive or Ambassador??

I acquired a 14K RGP square movement and case today. The movement is a 10A 15 Jewels with a circle symbol. No dial or hands. Dust covered trifold with dust cover intact and in good shape. It appears to be an Executive or maybe an Ambassador. Both have same case style. Crystal dimensions are 21.7 by 21.7 mm. Lug to lug is 33.21mm by26.6 mm with no crown. Trifold is in excellent shape. Movement is missing balance and balance cock as well as hour wheel. I think it is worth repairing since it seems to be a rare one worth the effort. I will post pictures as soon as I get it cleaned up.
