After the date specified in the preceding sentence such a filing shall no longer be effective even though the conditional sale vendor or the chattel mortgagee has filed with the appropriate town clerk the request in writing referred to in § 42-78 and even though the town clerk continues to keep the chattel mortgage or the contract of conditional sale, together with any such request, on file.
