Hi, I am rebuilding a dynascope RB-6. These scopes were made from about 1958 to into the 1980's. Is there any way to determine when an RB-6 was made. I found markings on to drive motor, 35674-r-6 1-80. Could the 1-80 be Jan. 1980 or is it something else? I need to replace the reduction gearing for this scope, if anyone has a motor, reduction gearing available please let me know. When did the first RB-6 hit the market and when did the last one leave the factory?

That's R_V_-6.

Yes, the motor indicates the date of manufacture. In most cases, anyhow. The RV-6 was continued after Criterion was bought by Bausch and Lomb, and, the RV-6 Dynascope was sold all the way up to Comet Halley time, around 1986.

Best bet for RV-6 parts is to enquire on the Dynascope Yahoogroup.

Bill,

Click on my name in BLUE. That will bring up my profile. Then click on Send Private Message. I have an entire extra drive unit that I will need for a while. We are using it as a reference while rebuilding 3 Criterion RV-6's. Total nut and bolt restoration.

Here is a pretty good history of the scope: http://www.company7.com/library/criterion_rv6.html

I have an entry in this forum on the restoration. Sean has been out of town for a couple of weeks so I've taken the time to revamp the shop. I will be painting my tube candy apple red, and the color scheme WILL be awesome.
