No. The real issued full-wrap for the 80/90's had the AV back to the saw(the 910 had the AV too, but the full-wrap was redesigned). I've posted pics before of mine and Robin landed one himself too. The mag case bodies are shaped for the AV and there is a pilot hole too for the screw to mount the AV. A helper I had broke my full-wrap by throwing heavy wood on top of it. That's what put me in the pickle I'm in. I have a supply of the unobtainium AV's for the full-wrap, but a broken full-wrap. I also have a steel, smaller diameter full-wrap that I'm using in the interim. It's cut before it goes to the saw body, but it's the only full-wrap I've seen like it. Doesn't look homemade, but could be I suppose.I thought these were originally cut like that - all of my 111 full wraps were cut too.
However, Tilton and Scotsco sold the saws out here with the full-wraps put on by American subcontractors. This is my theory, because I'm pretty sure they didn't leave Sweden with the full-wraps installed. But it was a factory endorsed and designed feature. I think it was the same on the Husky 2100...the full-wraps were put on in the states. The original bolts on the bottom of the Husky 2100 full-wraps were SAE, not metric. Who actually made the full-wraps I can't say with any certainty.
The 110/111/111S never had that AV feature and I'm betting what few 621's were issued with full-wraps didn't have it either.
