There is a lot going on about the key fobs. So I am summing up what I consider correct.
The first 2 types of Jaguar E Type Key fobs were the winged and the grawler type. This is proven by the very first 60 and 61 used manufacturer brand CVD with a larger V as shown on the pics. In about mid 62 the company changed the logo to CVD with all letters the same height. in about mid 65 a Newspaper add shows the 3rd design CUD. Few years later the company went bankrupt and CRAFTSMAN took over. Please use my search function to find more about Keyring in my bog. Be aware that also reproductions are sold as originals. This should help you to get what you want.
Both, the winged and the grawler do exist with the easiest logo 
Manufacturer togo time line : 61, 62 – 65 , 65 – 68
