I bought mine before the recent change to their website which is a mess now. It was $60 IIRC delivered to your door from India all sewn up in a strong neat parcel. They had been calling it a 'snap matchlock' which of course it is not. But it is a good example of a late 17th century military musket lock and at least as well made as a service lock of the day.
