The Webley air pistols that were distributed in the U.S. by the Stoeger Company are particularly sought after here in the UK and attract a significant premium on the rare occasions they do appear for sale. Being for export, these models often had some nice extras such as wood grips not available to the home market. Not sure how often these pistols are seen where you are, but it might be something you may come across if you were very lucky.
