Managed to get the 1894 Steyr apart. Unfortunately the one bolt was stripped so I had to drill it. Then once the stock was off, it took some heat and a easy out to get the bolt out of the hole. Otherwise everything else came apart easily (except the magazine, I don't think I will be able to fully strip that). Replacement screws are already on the way, and I am pretty close to being done cleaning the rifles.
Next step is to make up some dummy rounds to get the repro mannlicher clips fitted to the rifles so they feed properly. I suspect that shall be a pain.
