Cool Old Bay. I'd like to see your Volvo photos, maybe even borrow them. The trailer above is a 2600 and many of them (and old Bankhead B6s) were cut and reconfigured to 2600 Quickloaders. A few were stretched out to 48 foot high rails also. Here's the original 2600 brochure and a Quickloader with a Brigadier tractor.
