I had to get my LBS to shave about 3mm off (1.5 each side) the BB to make it work.
By the mid-80's Raleigh had gone to English threading. In the 1970's they were still mostly Raleigh's proprietary threading. You can have it retapped from Raleigh's 26tpi to the standard English 24 tpi but it will be a weak connection.
