'78 Pintail boom

Does anybody know who made the boom for the Pintail?

The "ears" on the casting that fits into the mast-end of the boom (the part you attach the tack of the sail to) broke off.

Now I need a replacement. I tried www.rigrite.com with little luck.

Thanks,
M

The boom and mast on my Pintail were made by Star Marine Hardware Inc., Soundview Road, Guilford, Conn. I didn't have much luck locating the company on the net.
