As chas57 says, old paint is notoriously hard to strip off, especially if it's lead-based and by the sound of it I would say there's a good chance that it is. If so you are right to be concerned about disturbing it, you don't want to release any dust into the air that can be breathed it. We do have a project that covers stripping lead paint that may be of use that can be found here: https://www.diydoctor.org.uk/projects/s ... -paint.htm
