MGM's record with original mixes hasn't been that great. It certainly won't be lossless.
The picture may fare better, but it's more likely that it comes from the same dated master used for the DVD.
Well, if that's the case, then perhaps someone can do a lossless capture of the audio from this laserdisc: http://www.lddb.com/laserdisc/07067/ML100872/Fistful-of-Dynamite-A-(1971)
