A motorcar of the era, ranging from a well-worn Model T to something considerably more refined.

A portable camera and film, useful for documenting evidence — assuming whatever was photographed actually develops on the print.

A simple iron bar for forcing doors, crates, and coffin lids. Doubles as a improvised weapon (1d8 damage).

A battery-powered hand torch. Reliable, but batteries are a limited resource and prone to failing at the worst moment.

Bandages, iodine, and basic supplies sufficient to stabilize a wound in the field.

An oil lantern with a glass chimney, resistant to wind and weather — invaluable when the electric torch inevitably fails.

A physician's bag of proper instruments and supplies, required for anything beyond basic First Aid.

For recording clues, addresses, and the last coherent thoughts before things stop making sense.
