I wonder what caused that?. The only flammable liquids forward of the cockpit bulkhead are 06A in a de-icer tank (unlikely, given the aircraft's location), small amounts of hydraulic fluid in the cowl flap selectors lines and the engine, hydraulic & Avgas fluids in instrument lines.
Good question , for the nose to melt off it would have to be a raging fire.
Jerry can of fuel near the cockpit and a spark ?
Looks repairable from the photo though, with a nose section from another aircraft.
With the rapidly declining market value of a DC3 airframe it's cheaper to just swap the good bits onto another airframe , too much work to save this one. Game over .
