Presumably, this bait is a factory trial production (prototype) of Zara Mouse lures. Marketed ones were first sold in the early 1990s (1991?), so I can imagine that this bait was made in the late 1980s or a little later.
The same body as Meadow Mouse is used, but the line-tie eye is different. On the belly and tail, it has holes for hooks, but nothing is marked on the body surface. The fluorescent red eyes are carefully painted, much more carefully than marketed ones, but the tail slit looks roughly hand-filed.
I'm very happy to get it in my collection. I'm afraid this bait is not good for fishing because of bad attachment of single weedless hook, but it is a good collectible lure.
