I believe that this is an Anton Model 5 prototype. It looks just like an old Universal Atomics 700 Model 4. The Universal Atomics Model 4 has a plastic case identical in appearance to this case but this Anton Model 5 case is all metal. I've never seen another one of these. Serial Number is 53. Looks just like a Universal Atomics Model 4 from this angle too. Case side label with check source underneath although it doesn't say so. No serial number on this plate. Picture on the right shows taped-on typed label. I assume that the 2-26-59 date is the date built or maybe the date it was submitted for approval. Here is a close-up photo of the Anton 700 Model 5 case label. I have no idea what is going on with this one. It says on the case it's a Anton 700 Model 5 but it's in the slightly larger Anton Model 6 case. I have 3 Anton production Model 5's and they are all in the narrower Anton Model 5 case. I origianally thought that this was a prototype for the Anton Model 6 but surely it would have "Model 6" instead of "Model 5" on the case. I don't know, maybe there was a wide-body Anton Model 5. The most interesting thing about this meter to me is that there is no serial number on it and there is no evidence of one ever being on it. The white tag tied to the unit has "Production prototype to be kept" typed on it. Click here to see the tags. Here is the taped-on typed label on this meter. The dates are almost exactly a year later than the Anton Model 5 at the top of the page. Higher-Range CD V-700 Modification Kit This one is not a prototype but a higher range CD V-700 using a special G-M tube. The following text is information provided by a Yahoo group CDV700Club member who had some info about this unit... "What you have is a CD V-700 that was intended for use with one of the B-2 aerial monitoring kits. The kits originally came with an OCD ITEM NO. OCD-D-101, TYPE A Geiger-Mueller Tube and a "stick-on" range change. The modification G-M tube and applique was manufactured by EON Corporation. That G-M tube was designed to be compatable with the CD V-700. Changing the GM tube effectively decreased the sensitivity of the CD V-700 by a factor of 10 due to the decreased volume of the G-M detector. Thus the ranges became 0-5, 0-50 and 0-500 mR/hr." What it amounts to is that all that had to be done is intall the higher range tube and stick on the applique to "change" the range of the meter. This is a Victoreen CD V-700 Model 6B. The modification did not change the model number of the meter. Here is a close-up of the EON G-M tube. The detecting section of the tube is the thin diameter tube in the center of the "caged" section. EON G-M Tube Kit Here is the EON G-M tube kit. The kit is just instructions, tube and a sticker. This kit could have been installed on any Model 6 or higher CD V-700. Here is PAGE 1 PAGE 2 PAGE 3 and PAGE 4 of the EON manual seen in the above photo. Special Thanks to Paul Frame for this kit!
