Hello Mazwork,
Please do have a look on a previous thread posted here on TOCH. I enclosed some pictures of this camera you do believe is from a 1º GavCa's P-47 D.

Hope you will find the "match". If you do need assistance to cross-check the Brazilian's Thunderbolts serial numbers feel free.
All the best
