Hello all,
What are your thoughts on the the collection significance between the original HP-35 and (I guess) version 4 with the key nomenclatures directly on the keys?

Not sure if I understand what you mean by collection significance. Obviously, a red-dot version 1 is much more desirable to a collector than a version 4. But a collector will also want to have all versions. The version 4 is interesting as the final evolutionary step of the 35, the first handheld calculator to perform transcendental functions.
