No endorsement or memorandum of any payment, written or placed upon any promissory note, bill of exchange, or other writing, by or on behalf of the party to whom the payment was made or was purported to have been made, shall be allowed as evidence of the payment for the purpose of barring the running of the period of limitations. This section merely limits the evidence which may be allowed to be given for the purpose of showing part payment which would bar the running of the period of limitations, and is not to be deemed to have any control over the effect of part payment which is proved by other evidence.
