This is a used Polaroid SX-70 Land Camera Alpha 1 that has been refurbished and modified by MINT camera to be able to use both SX-70 and 600 film (for lower light conditions).  This model is called the MINT SLR670a.  It is in excellent working and cosmetic condition.  

Information from Mint's website:
SLR670α is designed for maximum easiness to use. 670α is an automatic camera with advance shutter and brightness control.  It merges the best functions and features of Polaroid SX-70 and SLR680 into a sleek, stylish body.
We used the body of SX-70 and took part of the electronics of SLR680. That's why it is called SLR670α.
