Here's my first assembled Forge World Imperial Guard Tauros Venator. This has Tallarn models substituted. They're the same auto-gunner model, which isn't idea, but it works. The models sit up straight so they didn't fit perfectly. The roll cage needed to be modified to make it work, extended up front and the cross beam removed. The photos show I've got a bit more clean up work on the body.
Edit: Better photos after straightening the perpetually crooked multi-lasers.
