Vintage 9’-10” Hansen info wanted

Posting this 9’-10” Hansen for a friend, we are trying to tie down an approximate year and would like thoughts on the fin. It appears to be too large to be a reshaped D fin however perhaps a reshaped 50/50 fin? The fin base is about 13” and it about 11” tall. Any insight on the board is greatly appreciated. Thanks 





Other side of the fin

IS THERE A NUMBER ON THE STRINGER, NEAR THE TAIL?     IF YES, WHAT IS IT?      I’VE ONLY SEEN THAT FIN ON ONE OTHER HANSEN.       IT IS IN BIRD’S COLLECTION.

Bill, the report I have at this point is no number I will update if one is found. Thank you

My gut makes me think that is a late’63/'64  board.

Thanks Bill, that at least puts it in a window. As always your input is greatly appreciated.
