Were tank badges painted?

!960's two tone Slimline Dommy tank  badges were painted in the same colour as the tank bottoms .With the raised edge of lettering chrome.

... photo! As my tank is silver it would be unnoticeable if the background was painted the tank colour but I have idly speculated that a black background would look nice. On the end of a very long list of - mostly non-Norton - tasks in my virtual in-box.....

... do it the way you like it and let the paint code obsessives argue amongst themselves.

The best way to check authenticity is to look at period road tests , Bikes often borrowed from dealers stock.. And ask members who have owned the models from then till now. I had a two tone Norton in the early 1960's and have kept one for the last 36 years, only repainting when absolutely necessary through rust taking hold.  Factory photos are less reliable as pictures of pre production bikes got sent to the advertising dept sometimes. I am looking at one that shows paint missing from footrests , side panels missing tickler slot and tank badges that never reached the sales floor !.

... my copy of a compendium of Norton articles which includes road tests of Jubilee, Navigator and Electra from the Motor Cycle and Motor Cycling. The photos are poor quality and grainy but it seems clear that the Jubilee and Navigator badges have no paint but the Electra, which has a silver tank, seems to have a black background. To add even more confusion, there's also a riders' reports article on the Jubilee which is accompanied by two photos of different bikes which are unclear but definitely show the Norton badge with a dark background. Obviously real bikes (reg 620FXF and JPH431C) as are the others.

So as before, there's obviously no "correct" way.

Incidentally, that book - Norton from 1946 edited by Cyril Ayton, former editor of Motorcycle Sport, is a real goldmine. ISBN 1-870979-00-1 if you can find one. In fact there are a few listed: https://www.abebooks.co.uk/servlet/SearchResults?ds=20&kn=1-870979-00-1&ref_=ds_ac_d_14&sts=t

I dissagree ! , the badge would be painted the same colour as the tank lower ,white (dove).

Looking through the most excellent collection of Norton sales brochures .....assembled by the Editor, I notice that from 1960 onwards the Tank badges had various finishes.
Most of the Models (but not all) have the raised lettering (ie. Norton) painted Black.
This continues for 1961 and 1962.  However the new UK 650SS has the background filled in with Black whereas the Norton letters remain with a natural metal finish. 
Apparently the export models of that era reflected this change with background colours of Red, Silver and Black depending on the Tank finish.

Did Norton colour the tank badges to suit the model, one colour for, say a 500, another for a 600?

I can think of a couple of manufactures that did this, although smaller ranges of vehicles.

My unrestored ES2 slimline has green background matching the top colour.
