The Mila 47201 twin-spindle centre gearbox is a replacement centre component, not a complete multipoint locking strip.
The exact supplier row describes 47201 with 92mm and 70mm spindle positions. Do not replace that identity with 92/62mm dimensions from a Master or Lockmaster lock.
Confirm the legacy donor generation, connector style, retaining fixings and handle function. Similarity to another old Mila case does not approve an offset-to-inline modification or a universal outside-entry function.
Match the exact original case and lock generation, backset, spindle arrangement, case outline, drive connections and retaining fixings. Matching the brand or a single measurement does not establish a direct replacement.
A centre-case repair can retain the locking strip only when the replacement is an exact match and the strip, remote locking points and frame keeps remain serviceable. Have the fault and the complete assembled lock checked before assuming that the gearbox alone is sufficient.
