As per comments the single view of your CPT will be handled according to template hierarchy. Within appropriate template you can use template tags normally, so simply get_post()
without arguments will get you a current instance.
It is a little more tricky if you want to refer to a specific post in code outside of its context.
The most reliable within custom site is hardcoding its ID. Personally I also use get_page_by_title()
(despite name can work on arbitrary post type) which is easier for human to read, but depends on title staying unchanged.
