BSA mercury range

That's strange as the Mercury S and Airsporter S I have, both where jammed up with alloy heads and a massive space where the buffer washer used to be, so I think it's the whole range that suffered

Sorry, my mistake. Avoid the use of the earlier nylon heads. When they jam they really jam

You are correct but the old crumbly cheese buffer washer is the main culprit on the later models, that's why I always strip mine as soon as I get them to see what they are like inside, however good they look like on the outside.
