Oops! Sorry about the mistake concerning the hilt materials. No, it doesn't change the outcome. Sometimes a picture isn't worth a thousand words. Nothing beats actually handling the 'beast'. Espada had hilts of both wood and horn and the pic made it appear yours could be the latter. I still wouldn't classify yours as a true espada ancha, but more of a Spanish colonial cutlass. The majority of the short-sword types typically had singe-edged curving blades with slat-wood/slat-horn grips (an important difference here from your rounded grip) that were sandwiched onto/riveted onto the tang. Your grip really does match the Amer colonial patterns of the period, thus my initial guess.
