Rolleiflex Rolleinar Bay Size Markings?

[jlkphoto]

I've acquired an old Rolleiflex MX-EVS with the Xenar 3.5f 75mm. I

got several filters and other accessories with the camera. I know

this lens takes "Bay I" sized accessories but here is my question:

 

How are the Rolleinar sizes shown on the newer two-piece items?

 

I only have an older three-piece Rolleinar 2 that has a red "R" in

script on the rim. There is no "I," "II," or "III" after the "R."

 

However, when I look on EBAY at newer two-piece Rolleinars, I see in

red script, one of the following on each Rolleinar:

"R I"

 

"R II"

 

"R III"

 

 

Does the above translate to

Bay I, Bay II, Bay III?

 

If the rim of a Rolleinar has "Heidosmat-Rolleinar 3 RII," is that

a "Bay II" size?

Yes, R I = bay I, R II = bay II, R III = bay III. BTW the "R" comes from "Rollei bayonet".

When there was only one bayonet size there was no need to add a number. This is size I.
