I bought my first one in 2016 after reading Merkur had recently replaced their casting molds so every metal part looked very crisp however the plastic end knobs were very rough around the edges (literally!) They appeared to have switched to an inferior type of plastic... The blade alignment however was perfect.
Here's an album of that 2016 Progress:

Merkur have since sorted the plastic issue so now they have crisp metalwork, good quality plastic and still no blade alignment issues, which I can confirm having just bought another... Must say, yours looks exactly like the one I just bought (apart from the red dot, a DIY addition I presume as Merkur haven't done this for years.) Based on this I would guess yours is a couple of years old at most.
