Current production Bighorns and Wolverines have real Timney triggers too. Older models have Vehr/Velocity type triggers. So if you want a real Timney its worth paying the price for a brand new one.
BH's have excellent adjustable Timney triggers and Green Mtn barrels that shoot extremely well. They disassemble easy enough as they are plunger guns. My 2 BH's love .452dia 250-300gr jacketed bullets and Barnes bullets with black Hornady sabots, T7 powder and 209 or musket caps. I have a 24" blue and a 28" SS version.
