I was over at the Ligonier Highland Festival in Ligonier, Pennsylvania over the week end and I saw a formal (evening) sporran that had a functioning latch on the cantle. The latch was spring loaded and retracted by pulling up on the "top" latch button. Most of the ones I have examined in preparation for constructing an evening sporran have a snap enclosure that fastens behind the top of the cantle on the leather back piece of the sporran. Can anyone direct me to where I can find detailed photos or diagram/drawings (or both) of a spring loaded cantle latch. Thanks in advance.
