Hello, maybe Anne will shift my post to the animals, but this is a flask

I baught this because it is funnny and a bit crazy. I think for a lamp work it is to heavy, it is around one kg highest point 24 cm and from head to tale 23 cm.
I know this fun bottles are sometimes very old, but is this as well? I doubt a little bit, too good in shape, only some little cuts on the rim and one foot is a little bit sharpe. The horse stands only on the tips, so you canīt see scratches from standing. The glas is green greyish.
old fun flasks are often dogs, but I know that somewhere I saw a horse, but I canīt find it again. Is here a expert that can see by the apearence how old this might be?
looking forward to your input
you see, I like glass in all shapes and ages
