Custom master pages don't appear in all site collections within same App

Question

I created an additional site collection within an existing application which has a preexisting site collection.
The preexisting site collection uses a custom master page:
.../_Layouts/ChangeSiteMasterPage.aspx
that doesn't appear in
.../newsite/_Layouts/ChangeSiteMasterPage.aspx
Anything I need to do in
.../_catalogs/masterpage/forms/allitems.aspx
to apply the masterpage to the new site?

Hey,
I don't get the problem completely. I undestand that your custom masterpage, which you created once for an existing site collection, does not appear in a newly created site collection. So what where your deployment steps for the custom masterpage?
Generally you would create the masterpage via Visual Studio and deploy it within a feature to the catalogs library, either in web-scope or in site-scope. A feature event receiver applys the masterpage to the current website (in web-scope) or to all webs
in the site collection (in site-scope) on feature activating. But in both scopes you need to active the feature in every site collection (or website).
So please tell us how you deployed the masterpage.
