Tinker, will let you know what is available as soon as I hear from the seller, might be after new years. My brother used to have an Alex Henry 20 bore rifle and I had the next consecutive serial number Henry in .577 3". Both made for the Maharaja of Patiallah in 1874. Sold both of them, dang it! I also had a 16 bore Lancaster double rifle made for the Maharaja of Bulrampoor in 1876, cased with 16 accessories. Sold it too and wished I had it back.
Take care, Gary
