It doesn't matter who bought who, find somebody you worked with and ask them to confirm your experience.
To find them use Google, Facebook, Twitter any other social network.
I worked in Uzbekistan in one place 19 years ago. Not only the company is dissolved, even the building is demolished. But I found someone I worked with. Even though she is Germany, and I am in China.
And again 14 years ago I worked for one project I forgot the name. I found a person who headed that project through Google. He is in the States, working on another big project.
And so on ("Wow, you haven't changed!!! How do you do it?!!! How did you find me?!!! ha-ha, that was easy, the guy is a big financial director
)
Yes, the miracle of Internet.
