Ok, so if you can't read Finnish *Cough cough* like the 7 billion others on the planet, I suggest using google translate. UNLESS someone has the English version, this is the closest you'll probably get on your own. And before you argue that GT is really horrible and the worst ever, recognize that in this short doujin with simple sentences and pictures to help indicate the situation and idea of what's being said, the translation is very accurate (unless GT is extremely good at screwing up the situation perfectly). But yea, if you have an English version, by all means and all thanks upload it! And for now, here's an example of Google Translate:

Mitäs... Erica?
Ei kun sehän onkin Ursula
Siitä onkin aikaa, Eila
Olin lähistöllä tarkastamassa schwalben kehitystyön edistymistä.
Et ole muuttunut.
hauska nähdä taas
sinä olet ainakin muuttunut.
onneksi tulin käymään
kuulin tapahtuneesta, joten ajattelin tulla säätämään fliegerhammeriasi
lähetin siskollenikin kirjeen, mutta hän ei tullut edes tervehtimään.
kirje lienee jossain täällä

as long as this war is over, so what if ...
What do you ... Erica?
No, it is after Ursula
It's been a while, Eila
I was nearby to inspect the progress of the development Schwalbe.
You have not changed.
good to see you again
you have at least changed.
Fortunately, I came to visit
I heard what happened, so I thought to come to adjust the fliegerhammeriasi
sent a letter to my sister, but she did not even say hello.
letter is probably in here somewhere
^you get the gist ;P
