Rockola 453 question

Hi,

I’m (trying to ) restore a ‘74 Rockola 453 - in particular the front glass panel which has been smashed (presumably) and replaced with a clear pane of glass.

I’ve done the artwork for a new decal, but guessing a bit on the spacing and size of the little coloured rectangles that make up the centre of the panel.

If any 453 owners are feeling generous, could I please trouble you for the following measurements:

(Little) Rectangle height:

(Little) Rectangle width:

Black spacing between rows (height):

Black spacing between columns (width):

Many thanks,
