Looks like it could be a buckbee
I hate to say it but what ever someone is willing to pay. How much work does It need? Is it a Buckbee or a Dobson? what will it cost to get it playable and how much time do you want to spend on it? For $125 it might have that in parts.
The bad news is that these days it's seldom cost-effective to restore these old-timers, even if the needs are modest.
If it was me I would buy it ,restore and keep it to sell later. I just found the tuning pegs I have been looking 15 years for a Buckbee I have. No hurry for these things.
