McCulloch MAC538 chainsaw for parts (Leighton Buzzard LU7 3)

McCulloch MAC538 38hp chainsaw, spares or repairs.
This was given to me by my mother in law to see if it could be repaired after her garage flooded and this sat in water for a couple of months. I’ve had a look and can’t get some of the parts anymore. It will need at least the following :

1. A new bar, what’s left of the chain is rusted to it.
2. A new chain
3. A new rubber gasket to fit the air conveyer (not listed is any parts diagrams as can only find parts diagram for the 538e which is different to this) as it disintegrated into about 100 pieces when removed.
4. The starter prawls and springs need replacing.
5. The pull start is in poor shape and doesn’t recoil and the plastic to pretty chewed up.
6. The engine, carb and flywheel will need a complete strip down and rebuild.
7. Electrics are likely shot as when turned upside down large amounts of water came out of the handle which had been sat there for months.

It may well need more work than this, once I realised it was beyond economical repair and could’nt get some of the parts (such as carb and gasket for air conveyor I didn’t go any further) it does have a kick back brake but this will likely need work aswell to ensure safe operation given the condition of the rest of the machine.
