Necropost, but that's a No. 6. Obvious visual differences between the two are:
-the No. 5 has a thinner front bezel than the No. 6.
-the No. 5 and 42 keys, the No. 6 has 38 keys.
-the No. 5 has no cover for the typebasket's front edge, while the No. 6 does (though it's sometimes missing).
-the No. 5 has two front carriage wheels, while the No. 6 only has one.
-the No. 5 has a bare wood spacebar, while the No. 6's is black.
Upstrike Remingtons had at least three different decals styles declaring their model number; yours looks like it previously had the "rectangular" type (for example, this No. 8 https://typewriterdatabase.com/1903-remington-8.15215.typewriter), but after it wore away someone replaced it with the more common "large" decal.
In a nutshell, you have a No. 6 whose front decal wore off and someone replaced it with the correct one of a different style.
