A question for bf109 'experten'

[Biggs]

so I came across a couple pics of an Emil that took me by surprise. there is something odd about the wing armament configuration, it appears to have 2 access ports for mgs/cannon, instead of the more customary single wing cannon port.

can any of you tell me what variant this is an how common it was during the war.

heres a BoB emil at the imperial war museum: note 2 wing ports.


and the second i found was this russian captured Emil... looks to be a later E series (pointed nose cone)... one port being occupied by a cannon, the other an MG?


what gives?
