An Italian Bill (Roncone) for comment

[BUCC_Guy]

Do any of you gentlemen have thoughts or details on this Italian Bill?

I found one of similar construction (diamond spike, hard angle hook) previously sold by Christies.

Is it a safe bet that this one is likely 1520-1530?

My initial thought was that this one was indeed earlier than most on the market as construction is a bit more crude than the more refined, sleek Bills we see later in the 16th century. The hook angle is closer to a 90 degree angle than most examples.
