Nice, the OM4 and OM4T only comprises of 4 pieces of leatherette, the two back pieces are squared off, and the front pieces of a gentle curve for the lens mount. The most complicated part would be to cutout/drill the two holes for the self timer/silencer, and grip attachment screw hole. It looks like you can just put the pieces right over without the removal of any parts. I will know soon enough. Just got some brown lizard skin and sharkskin inbound as well.
Yeah I have a black OM4 and a chrome OM2N so I think red for the OM4 and white for the OM2N, I don't know if he combines postage, the wording on his site is a little unclear. But anyway I am sending the OM4 to Camtech for overhaul as soon as the kit arrives from Aki Asahi so he can fit it while he is doing the overhaul
