      Hello Everyone

      Picked up what I thought was a presnetation.

      It has the La Hiff's adjustment, the "Gold Plate" and red finger pieces.

      However, the base is glossy gun metal grey color.

      According to my readings, all presnentations had chromed bases.

      The photo was black and white so I didn't looked at the base closely.

      Was fixated on the La Hiff mainspring adjustment.

      My question is :

      Has anyone seen a presentation with other than the chromed base?

      Tnx Fernando N2FQ/6

        This sounds like a "parts"unit, which the factory did do from time to time, but as far as I have been told NEVER with a Presentation model from that vintage (year). There apparently were some bugs (test bugs ?) with the adjustable mainspring, but they would have been serial numbered many years before the one you have.

        Could be someone made up the unit AFTER it left the factory. <- To me that seems like the most likely answer. If you didn't pay too much for it, it should be very easy to enjoy having a bug with an adjustable mainspring !! (Right now that is the preferred bug in my shack.)

            Hello

            Thanks to everyone who responded. I do have French's book
            and had consulted it. I also spoke with Vibroplex
            while ordering the top jeweled screw and
            Mr. Robbins affirmed that all presentations come with chromed
            bases.

            I suppose that it could have been misrepresented although
            when I purchased it their was no mention of it being a presentation
            model.

            I'll get it going and see how it plays.

            Again thanks to all who took the time to post.

            The key, a Vibroplex Presentation model made in 1966 by Vibroplex of 833 Broadway, NY, NY was ordered with a standard base instead of the chrome base. In 1966
            Message 5 of 8 , Mar 5, 2011
              The key, a Vibroplex Presentation model made in 1966 by Vibroplex of 833 Broadway, NY, NY was ordered with a standard base instead of the chrome base.  In 1966 the standard base was gray as is this base.

              Of course, a standard Original could have been dismantled and fitted with the "Deluxe model" yoke which had a tapped hole as this one indeed does have for the attachment of the grounding braid, jeweled trunnion on the top, and bottom, the special lever of the Presentation which was slotted on the top for the removal of the main spring and had two tapped holes for machine screws to hold the main spring secure.  Then add two red finger pieces, and a red circuit closer knob.
              And to top it off - literally - the threaded red plastic piece that was used to seal the hole left by the short jeweled trunnion screw at the which had been changed in the Deluxe line about 1948.

              The cost of the individual parts would have been prohibitive - Vibroplex didn't sell the parts wholesale so you could "kit" a key.  Only if the owner ordered the key from Vibroplex or if he worked there (same thing) could he have made the key economically.

              The only evidence that it is a modified key is that the shorting braid isn't original - the original grounding braid was thinner and was a braid that was either tinned or silvered or made from tinned strands.  However, most people who take apart the Deluxe type keys for cleaning of the bearings forget to remove the thin braid and end up breaking it.  So they replace it with some sort of stranded wire.  These days I use "Solder Wick".

              So Fernando, it seems like you have an authentic gray based Presentation - perhaps ordered by the Navy or someone who liked battle ship gray.

              If the gray base is as well taken care of as the fragile gold plated top, you can be assured it is indistinguishable from "factory made" as everything is correct on the key.

              Very 73,

              DR

                Hello David

                Firstly let me say thank you for you detailed analysis.

                I'm delighted to read what you've said and consider myself

                fortunate.

                The base is in very good condition. What did caught

                my eyes though, was the new damper mounting screws.

                Anyway, DR.. take and thanks for taking the time.
