Are there two Raleigh bicycle companies?
There are license branding. 
For example Raleigh is sold in Japan through a Japanese bicycle wholesaler that design Raleigh bicycles to be adapted to Japan local trend.
The "Japanese" Raleigh are made in Taiwan and China and have not much to do with the original brand except the name and vintage design inspired by the original models of the 60's and 70's.
Many brands do this.

Your bike is probably of better quality than lower priced model.
You have to compare specification to be able to determinate if your bike is "lower" quality bike or not.
