how to call unique header.php file for a unique sidebar.php f

I’m trying to create customized page with a different header. The only thing different about this page is that it will not have a banner at the top but everything else stays the same.

So, I know that I have to create a new page.php like so;
<?php /* Template Name: Title */ ?>

But then I tried to create a new header.php file (I named it header1.php )and get the new page.php file to call it. This is what I inserted into the new page file;

<?php get_header1(); ?>

But this doesn’t seem to work. Can anyone help?
