Now I understand now Tamid the best reference for the correct gun manufacturers label including changes over their productive years. I have found is Peter Dyson's internet site, if he stocks it I have found they are always of the correct design for the time.
The three photographs I have added are for the label of a Purdey case I renovated, I wanted the 314 1/2 Oxford street address. The first was an original 35mm colour film photograph I took of a genuine case label, using film gives a far sharper initial image. The second image was converting the colour image to black and white then digitally remove the blemishes using a simple photograph editor. The third is a black and white film photograph whose negative was used to produce a bromide paper print to the correct label size but this is intentionally over exposed. Doing this burns out the light parts of the photograph leaving just the print. The photograph is then scanned and the print digitally enhanced so you have a clean perfect black and white label to print onto the correct paper. I do hope it makes sense because it is relatively simple but needing a real film camera, but it may be doable with a digital camera though I have never managed to make it work.
