Repair Kit

2 on every difficulty:

• Yard, Courtyard: in the crawlspace under the Main House porch; peel back the corrugated iron sheet between the two sets of steps and break the box (ch03). Madhouse: under the boarded-up window in the half-hidden SE area.
• Testing Area 2F, Supply Room: examine the dummy head with the hat on top of the cages (NE corner) while carrying the dummy-head Treasure Photo (Main House 2F, Storage, on the stool NE) (ch04).

Turns the Broken Handgun into the M19 Handgun and the Broken Shotgun into the M21 Shotgun. Nothing else uses it.

There are enough for both: the first on the Broken Handgun (ch03), the second on the Broken Shotgun (ch04), once you get it back from the statue with the Model Shotgun.
