Based on my additional research in accordance with instruction manual and relative document for G4M1, it is predicable that the wreckages are G4M1 Betty’s one.
Please refer to following reasons.
1.Manufacturing number 5194
5194 is deceiving number of Mitsubishi G4M1. Actual serial manufacturing number is 194.
In accordance with data book, 5194 has been captured by USA
2.Bulkhead
The construction is exactly G4M1's one.
3.Wing attach point
The construction is exactly G4M1's one.
4.Connection point
The construction is similar to G4M1's one.
5.Wreckage (Circular casing with bended rod)
The construction is exactly G4M1’s main gear mechanism.
Circular casing is reduction gear and crank extended from center of gear casing.
Bended rod is connecting rod between crank shaft and main wheel spoke.
Judging from the situation of bended connecting rod, the Betty’s gearing system is concluded landing preparation, and crashed by rough landing.
6.Wing bomb rack shackle
This is not wing bomb rack. It is very easily identifiable that the rack are installed in the bomb bay of G4M1.
7.Oleo wreckage
This cylinder is exactly oleo for G4M1’s tail wheel.
8.Landing gear strut
This wreckage still unknown. I expect the part will be assembled around engine system.
9.Wing tip
The photo of wing tip wreckage indicate that shape is most similar as G4M1 BETTY’s one.
