I have some leather slings sent to me by a friend on the Curio & Relic collector's e-list for Swede '96 that work fine on my VZ24 ..just loops and buckle at one end and a button and hole at the other... They are not pretty, but they work and with some attention, perhaps they could be cleaned up for display.
Contact me off line so I can send you one for the cost of your package, return address label, and a Priority Mail stamp
