Trying to see what can be done with an 1894 Elsie barn find that's rusted shut. Good wood, 32" damascus, Grade 2. Parts of coming off ok with some Kroil and gentle coaxing, except for the top tang screw and trigger guard screw. If the wood can be removed without damaging it, it will turn out nice, bit the trigger guard's got to come off for that to happen. So far Kroil and heat. Any suggestions beyond repeated use of those two things?

Thanks.
