Please help with aircraft infor

[gearphoto]

I have taken some photos of An2 of Vietnam People Airforce, however could not find any information about the aircraft (such as construction number). Could anyone please help me to find the information which are used to complete the form for submission pictures in Jetphotos.

Thank you very much.

An2 - Vietnam Peole Airforce
Reg: 101, 105 and 107...

I would upload with the registration but leave the c/n field blank. ( don't type "Unknown", just leave it blank. )

Vietnamese c/n's are almost impossible to obtain unless you can get to look at the aircraft data plate. Even the great guru site of military data, www.scramble.nl doesn't list Vietnamese data.
