check this side www.woessner-kolben.de
in januari i put a woessner piston in my huskie ww250 model '98, that is the same cilinder as you have.
It is forged, so even stronger than genuine and way cheaper.
I just purchased it via my dealer. succes
Have u checked the site. I believe it is on there, the price.
I believe it was approx 200 dutchguilders, the original pistons were sold for 400 dguilders.
