If you want to keep the original Blenheim cockpits in your DBW, you can delete or disable all classfiles not modified for this mod (check dates) and the 3do/Cockpit folder. This actually leaves only three classfiles and the contents of 3do/Plane/BlenheimMkI(Multi1) in my fix into Blenheim_Sarja_I folder.
After this all DBW Blenheims work like before and I can even fly this new Sarja I version with the DBW cockpit!
Unfortunately, there are some bugs with Sarja I:
- Cockpit view has ugly parts of external nose visible in lower nose windows because the code that hides external nose in cockpit view doesn't work.
- Top gunner position has older 3D like in this mod originally and unlike any DBW Blenheim.
- Top gunner position is named Bombardier and is linked to the health of bombardier instead of the gunner itself. This bug also appears in this mod originally but not in DBW Blenheims.
BTW, I also had parts of external nose visible in both fighter versions, but it is not because of this mod. To fix that I had to disable 6FCD5CC80BE155B0 in V2 Gear Damage mod, but that also removes gear damage mod for Blenheims.
