I have an old Symmons tub-shower mechanical mixing valve from the 50s or 60s, which is no longer mixing in enough hot water. Hot water to sink and other shower is plenty hot. Flow control spindle is easy to remove and looks OK, but replacement parts for this valve are no longer available. I did replace washers and gaskets when that kit was still available, and the valve seals well and has plenty of flow. Would enlarging some of the flow holes in the spindle increase the hot water? Any other possible fix without new parts? I'd sure prefer to stay with this valve at least a little longer rather than removing wallpaper and wallboard to install new valve, which might be quite a job with the old pipes
