The shorter post is the Record Superleggero (SL). It is easily identified by the drillied hole through the pivot and the camfered edge up by the head. The wall thickness is less than on Record posts. The one you have looks cut down, but it may have come in a short version, like the Record posts did. The clamp parts are not something I've seen before. SLs typically come with the steel clamp pieces of the standard Record post. I suspect that the person who suggested that these may be old Lambert parts is probably correct.
The other post is standard Record. It is old enough to have the small lettering and no min insertion line. When the NR posts came about, the Record became the Gran Sport. The NR was like the Record, but used the alloy lower clamps and the thinned-down upper clamps that had been developed for the SR post.
