Looked over the Brooklands this morning, seemed in excellent condition. Managed to take some photos of the frame, looks to have the A brace welded in. The owner said her late husband looked for a newer frame but the lower portion of the frame appears to be that of the earlier builds. Not sure though.
Unfortunately the pictures are to large to attach here. If anyone is whiling to give the photos a look I'd be happy to email or text them. Also, the owner had purchased the front suspension geometry correction kit. Would that be needed if the frame was newer?
The anti-bump-steer or “Comfort Kit” has been standard for a good while, if you have it then the problem is solved. From the small number of photos the frame looks to be in good order, maybe only a dry-miles vehicle? It still has the old bottom wishbone brackets, MMC will replace theses for circa £900 or for free if there’s any cracks in the vicinity. Another fail point is the front facing voltage regulator. If it’s on rubber bobbins and square it will probably fail at some point and need replacing with a Harley unit that won’t need the rubber bobbins and is mechanically a direct replacement but will need minor fiddling with one battery terminal washer that is too small.
