I agree, decomp processes first affect the pelvic area, starting often within a day after death, depending on climate.
However, top surgery and a nosejob are already fairly extensive and distinctive, regardless whether she kept their male bits downstairs or not. Where in the 1970s could a male asab get top surgery AND hormonal therapy? It was a time where hormonal treatment was in its infancy. I think most transwomen went abroad to Brazil or Thailand back then for surgery
And the ones who got surgery were just very few. Was there an option to get it in the US? A lost piece of transgender history.
Also was there a transgender or genderqueer scene locally in the 70s and 80s? Gay and lesbian, sure, there was - not as well documented as it would deserve but it existed and was fairly vibrant. But was there a trans community or some lgbtq+ clubs open for everybody?
We need to bring this sweetheart home. Someone has to miss her.
