I think that receiver is too close to the Marlin 100 to have been made by anyone else. A unique feature of the 100 is that the bolt locks into the loading port, something no other Marlin or any Savage/Stevens does. The trouble is that some other stuff, like the extractor, doesn't jibe with the 100.
The odd bolt handle appears to be a gunsmith job, put on when the original bolt handle broke off.
Of course, it could have been made by one of the many makers whose products have not been well documented, like Crescent, who made guns under dozens of trade names.
