This is the standard 'Norton' motif in black (with Reg'd Trade Mark in small lettering underneath) fitted to almost all painted/lined Norton petrol tanks, from the late 1920's - early 1960's. They are of the highest quality, do not shrink or crack and are the same ones I have used on my own tanks for the last 30 years
You may see some photographs on the internet of single cylinder Norton's with different size transfers - but these are the correct ones - both in size, colour and style.
Note that the backing paper colour can sometimes vary from the photograph by batch (either an off white or darker bluish are the most common) - but the transfers themselves will always be the same. (our latest batch have a slightly darker blue backing paper than previous batchs)
Fitting: All transfers are supplied with fitting instructions, but an important point to remember when fitting transfers - do not paint or lacquer over them until they have thoroughly dried. To be safe - I always leave at least one week after fitting before I then lacquer over them. Failure to do so can result in the transfer crinkling slightly - as the adhesive under the transfer has not had time to fully harden to the underlying paintwork
