Where a simple signature on a blank paper is delivered by the signer in order that it may be converted into a bill, it operates as a prima facie authority to fill it up as a complete bill for any amount, using the signature for that of the drawer, or the acceptor, or an indorser; and, in like manner, when a bill is wanting in any material particular, the person in possession of it has a prima facie authority to fill up the omission in any way he thinks fit. (Amended 31 of 1981 s. 65 )
