Question about Werk number

[KrisJG3]

Dear Collegues from Forum,

Please inform in which places and how many was intalled a id plate(s)/Flugzeug Schilds and on which details (engine,fuselage ,.....) with Werk number for German aircrafts:

1) Bf109
2) Fw190

I think about id plate from attachments and like here:

Is it possible that Werk number of aircraft was also mounted on the engine ?
For sure was painted on the fuselage.

Source of second photo (interesting article by the way) look: Horst Walter Petzchler passed away on May 16, 2011

(This information will be useful for us during legal exploration of places with two German fighters - we have to know how big is probability to find plates with Werk number.)

I see here taht also was mounted in FW190 on the:

"...The identification tag riveted to the fuselage frame tail section stating 156 and Werk nr. 1816 ..."
