Although I have been collecting sandcast Honda's for about 15 years, I am a bit out of date on their values now. I have a bare sandcast frame and engine cases, including correct oil pan and 1969 title, which have been sitting in my garage for over 5 years while other projects took priority. I  am debating on building it or selling it now. Numbers are around 3000 and within 300 of each other.  Have any sets like this traded lately, and at what price ?
