1. Two or more municipal corporations may by agreement provide for discharge by the police department of one of them, on behalf of the other or others, of the duties provided in subdivisions three, four, five, six, seven and eight of section two hundred fifty-three of the personal property law and in sections two hundred fifty-four, two hundred fifty-five and two hundred fifty-six of such law, with respect to property or instruments deposited with the police of such other municipal corporation or corporations and may designate a police officer or other public officer of one of such municipal corporations as the person to whom such property and instruments shall be transmitted as provided in subdivision two of such section two hundred fifty-three.  If pursuant to such agreement property or instruments deposited with the police of a municipal corporation are transmitted, together with the reports of the persons who deposited them, to a police officer or other official of another municipal corporation, the police of that municipal corporation shall, with respect to such property or instrument, be deemed the police with whom the property or instrument was deposited and the police having custody of the property or instrument for the purposes of subdivisions three, four, five, six, seven, and eight of section two hundred fifty-three of the personal property law and for the purposes of sections two hundred fifty-four, two hundred fifty-five, two hundred fifty-six, and two hundred fifty-eight of such law.

2. Such agreement may also provide for payment to the municipal corporation by whom such duties are to be discharged, by the municipal corporation on whose behalf they are so discharged, of such amount or amounts as may be agreed in reimbursement of or otherwise on account of expense incurred in the discharge of such duties.

3. Such agreement may also provide that the police of municipal corporations on whose behalf such duties are to be discharged shall make and keep records of reports and deposits of found property and found instruments, and of receipts given therefor, in such manner and by use of such forms as shall be specified by the police of the municipal corporation to whose police the property and instruments are to be transmitted.

4. If incorporated in a resolution of the governing board of a municipal corporation on whose behalf such duties are to be discharged, such agreement may also provide that rules and regulations enacted pursuant to section two hundred fifty of this chapter by the governing board of the municipal corporation by whose police such duties are to be performed shall be applicable to property or instruments found, or of which possession is acquired, within the jurisdiction of the municipal corporation on whose behalf such duties are to be performed.  A resolution of a municipal corporation on behalf of whom such duties are to be performed, incorporating an agreement so providing, shall be deemed an enactment of the rules and regulations so made applicable as rules and regulations of the municipal corporation on whose behalf such duties are to be performed.
