Yes, the hull bracket on the MK-I* is cast. Bronze. Hence few and far between of the originals exist. Ben H. had copies made circa 2012/2013, in woodpecker lip cast steel. The MK-I* bracket is not interchangeable with the MK-II*.
(I am reliably advised by a good friend that original examples of UC MK-I and UC MK-I* smoke discharger hull mounting brackets can be found in steel) Kia ora L.E.
While the Quebec made Ross M-10 .303BRIT action was used for Canadian Universal Carriers, the MK-I* was remotely fired by attached cable, while the MK-II* was a conventional 'finger on trigger' release.
