It's looking the biz - nice work !
You will probably find that printing your own instruments as decals, or even on paper, in anything less than at least 1/24th scale, will not hold enough resolution to show the dials clearly, especially on the smaller instruments, such as engine dials etc.
There are a few companies that supply decals, in most of the major scales, one of which is shown below, this being their RAF WW2 type, in 1/48th scale, with USAAF, Luftwaffe etc also available.
These are
separate decals for each instrument, and can be used, straight off the sheet, just by cutting out each decal - the carrier film is minimal, and circular. Full instructions and identification of each dial are provided.
