Hi Rody, according to our spec sheets none of the screaming eagles take a 47 inch string. And according to our sheet the serial number sounds like an H 500. If you look inside the cams at the end of the cables you should see some color on the ends. And we should also be able to find out the correct string for the bow also.
Once we know this we can check to see which bow you have. As for a handle I have not been able to locate the rubber grips that were standard back then and would recomend Bob at www.GitaGrip.com
The limbs have Screaming Eagle on the lower and Oneida Eagle on the other.
The Tag is a stick on tag that looks original and has al above infofo on it . I just noticed the the 50 is the lower wieght range.
The tag looks original as it has the patent numbers on it. The tag is hand written.
One yoke cable has blue on it the other looks to be black.
The power cable has no colour on it.
