I was browsing the VIA Wikipedia pages, looking at lists of CPUs (as one does) and I noticed some unusual CPU models I have never seen before.

https://en.wikipedia.org/wiki/List_of_VIA_C3_microprocessors

I have a VIA C3 1.0A and 1.2A - neither are that hard to find. What I haven't seen before are the 1.3A and 1.4A PGA packages. I have been able to find the 1.3A "Mobile Pro" CPUs in BGA but I have never seen the 1.4A models in any package. I went looking on google and I can't find any image or any mention anywhere of a 1.3A PGA package and I can't find anything other than digital rendering of the 1.4A, 1.4B or 1.4C anywhere.

Were socket 370 versions of these processors ever actually made? Does anyone have one or has anyone seen a picture of them?

Just because I am curious, do you know if there are any BGA to PGA pin grids that work to adapt the BGA packages to socket 370? I think likely not (its a different pin layout) but assuming you wired everything correctly I would think they would be compatible.
