This is very reminiscent of how I recall the regular brand (red wax) from the 1980's and earlier. The current MM is certainly worthy (improved I find over the last few years) but not as rich as, and without the wine-like note noted by Emerald in, its ancestor of 30 years ago. Still, there are some similaritries. One is the pine nuts noted, it still characterises the brand. Today I get whispers of honey, wheat, pine nuts and butterscotch in the brand, it's a good dram.
It's a rare event to be able able to taste older Maker's Mark, I've only had one chance, courtesy Professor Veach, and it was superb, much like Emerald described.
