Here's a random translation I did of a Spanish sub of Flashman Episode 20 using my mediocre high school Spanish skills. It's probably not accurate, there was some guessing involved, but it's better than nothing!
I might translate some other shows if they have Spanish subtitles, should I find any. Flashman episodes #22 and #23 are available for translation, also.
Credits to BunnyHat for the raw and smcproducciones.mex.tl for the original subtitles.
