They did not. If it's got the screw in handle it's definitely old. I've got a line on a couple old 7" models, I'm hoping to get one today or tomorrow. When that happens I can do measurements and take pictures of the blade carriage area and flighting and maybe come up with something. Or I can just pull the blades off the new 8" and measure the carriage and maybe you could work it out that way. I think you might be able to make the new 8" work OK with 7" blades but you'd have to take a grinder to the blade carriage. With how much blade already sticks out on the 8" I'd be hesitant to do that and then put 8" blades back on it. And even then the flighting might still bind.
