Yup! I just took a careful look at some pictures of a 1973 Raleigh International that I picked up this Spring for twenty dollars. In my opinion, the bike you have sent pictures of is indeed a Raleigh International. That said, keep in mind that I am not an expert but I do like Internationals.
As for the asking price - NOPE! Wayyyyy too much in today's market. But two years from now, that will come close to the going rate. My opinion of course, not a statement that you can make money on. I should add that I sold the pictured frame set for $400.00 USD.
