Hi, Pat-san.
Appreciate your kindness, and I was able to read the Ostpanzer site using Babel Fish. It could get good translation that wrote simple Russian.

As a result I found there is new looking information that captured Pz.1 was possibly rearmed by Soviet machine guns DP -28.
Some photos of CV33, T-26 and Vickers Mk.E in URL I pasted seem to have been taken in Yasukuni JInja. And Pz.1 bottom of page was taken after target examinatio by IJA 37mm Anti Tank Gun. It's mysterious how those became afterwards....
Regards.
