The only change of any consequence was the addition of LotuTec. The eyecup design (to slightly smaller, rounded, softer) was changed prior to that, and I do like the new style better, but they are available from Zeiss and are easily replaced. The Victory FL name was added to the armor even later. The x32 FL ocular rain guard was changed from a loose oversize fit on any eyecup, to (very briefly) a very tight fit for the new style eyecups, to a slightly loose fit with tabs to hold it gently in place on the new eyecups.
I think the square-corner eyecups of the unit you are looking at reveal that it lacks LotuTec.
