During my recent visit to the U.S. I came across a H.D. siren in an antique shop in La Crosse and thought it might help someone if the address was posted here. I didn't enquire as to the price but it looked in very good order. Interested parties should contact:
Hank or Joan Vogel
Rivertown Gallery Antiques
110 South Third
La Crosse, Wisconson Ph # (608) 782 6533
Bear in mind that this was in early September and as I only got back to N.Z. very recently it could have already been sold but could well save someone a lot of hunting if it's still there.
