I'm running the risk (again!) of being a tad pedantic here, but... are you sure it's a Va??
Is there a removable 'wheel' on the right side of the camera with the numbers '12' or '16' or even '24/ on it?? If yes, then lucky you - it's a late model Vb on your hands, dating to the late 1960s to early 1970s.
IIRC, it was known as the Vb model III, but then again I'm going on memory and with a guess and I may be wrong on this, as I so often am on such things.
Is that dirt of a touch of rust on the 'M' button on the front?? Whichever it is, it may clean that up nicely with little or no effort.
Whichever model you have, it looks in VG condition, and you have a wonderful camera on your hands. A great little shooter, the lens has heaps of character and personality, and it doesn't have the Rollei automatic film loading system, which can be a problem with the older cameras. Takes Rollei bayonet I accessories which were made for the legendary Rolleiflex automat and sold by the zillions, not expensive. Win-win for you.
Use it and enjoy it.
