Not entirely sure what you're after here because you didn't make it clear but...

NORMAL Tenzans are craftable. There's a bunch of recipes on the page for the aircraft:

http://kancolle.wikia.com/wiki/Tenzan_%28Heavenly_Mountain%29

Tenzan Model 12 (Murata Squadron) is obtained by having a non-heartlocked Type 97 Torpedo Bomber (Murata Squadron) equipped on Shoukaku who is set as your first fleet flagship. Then activating the quest mentioned above and then scrapping two normal Tenzans one at a time. Then you clear the quest and it turns your Type 97 into a Tenzan Model 12.
