Talk:Polikarpov I-185

Problematic ISBN
Can someone verify the citation information for the following book listed as a reference in the article? I am not able to locate a book with this ISBN or title anywhere. I have found other books, but not this one, by the same author (Mikhail Maslov). Thanks for your help. Keesiewonder talk 23:39, 7 February 2007 (UTC)
 * Маслов, М. И-180 / И-185 (Maslov, M. I-180 / I-185). ISBN 5-93848-003-7

Phrasing
, the word "different" is necessary because saying that the plane flew with three engines makes no sense. That raises more questions for a reader than it solves.--Sturmvogel 66 (talk) 14:22, 10 June 2016 (UTC)
