There were several 75mm figures from Hinchliffe; sculpted by Ray Lamb & latterly by Julian Benassi. There were also 80mm scale figures sculpted by Paul Knight, Julian Benassi & latterly Alan Caton. In conjunction with these there was a 75mm scale Renaissance/ECW Cannon & Limber to accompany a 2 horse team from the same period. (I painted this one for the proposed box art of a combined kit but the release was cancelled when the Hinchliffe range was sold to Skytex.) They also produced at least 1 French Napoleonic cannon in 75mm scale. One of the Alan Caton figures was of a French Horse Artillery of the Guard Officer leaning against the cannon wheel.
At best I presume that Skytrex still have the moulds but I understand there are no plans to rerelease any of the range.
