Very ballparkish and mostly because of the intact mum I'd say about $300 these days. Not sure about the trigger guard/floorplate. Hard to imagine someone making one from scratch as common as they are but I don't recall them being quite that rough either. Guys tend to ask more than that but I don't see anyone picking them up for much higher. Also depends on condition, you say it's very nice but a collector is going to adhere to a much stricter grading scale. Your very nice may be their good. Photos would always help.
