Paul, I would tend to think that your spear head has a way too common profile to think it's Roman. It may be one of the spear head used in the early roman army, but the way the head is attached to the wood differs from what I've seen in many reference books and studies. It cant be confused with the well known Pilum as this one had a longer and slimer head. Most of the time, there also was a counterweight to increase range of the launch. Another kind of spear was used in parallel, the Hasta. In this case, same thought as for the early spears. The wood attachment part differs from what we can see on various sources and studies. Late roman infantry man used the Pilum but also the Spiculum. This particular spear could be what we're looking for. However, some details differs from your example displayed here. A better view could be useful. Is there a spine on the flat part of the head? Can you get a picture of the front side of the head so that we can figure out a bit better what a tridimensional view could give. Also what size is it? About the arrow head, I would say that it's a Roman. I have pictures of the same arrow head in a book about the early Roman army. Here's a picture of the same head I have on my hdd : Hope this helped, Best regards, Nicolas
