Took a look at the WB horn at Walmart yesterday, I think it was $6.99 per horn.
But I was NOT impressed with the size! I think they must have come from baby water buffalo!
I spent a few years in the Philippines, mid '50's. I was 10 when we moved there, almost 13 when we left. The people who lived around us when we lived in town (Cavite, across Manila Bay from Manila) had water buffalo - carabao - to tend the rice and cane fields. Huge animals, and quite expensive. They usually detailed one young lad to ride herd on them when they were not hitched to a plow.
Those big beasts, black as the ace of spades, easily weighed 2,000 lb, and the horns were about 15" across the base, and curved around to the face, most horns being in the neighborhood of 2' from base to tip.
Quite obviously a different species from the Indian water buffalo! I imagine you could have made an entire fore end from one of the Filipino buffalo horns! My mind reeled picturing one of those making a huge muzzle cap! Or you could use one as a powder horn for a small cannon....
The small black one I got will make a splendid ramrod tip, or fore end tip for a half-stock.
