You need the help of a gunsmith
[Edited by crazy_driver]
If you can manage installing the loading gate, hammer, trigger, and tightening the barrel, which will be loose if the gun has had any use in the last 40+ years of its existence, then you should be able to handle the most difficult part: Install the long heavy spring located in the handle pushing on the hammer. This last step required me to drill extra holes in my bench vice so I could pretension the spring for placement. If this is beyond your gunsmithing skills, the operative word here is "gunsmith" like the advice of the first answerer.

WARNING: Do not drop especially this (or any) gun. Murphy's law dictates any dangerous spring loaded weapon will land on its weakest part. For this gun in question, that would be the handle. Any large abrupt shock to the frame and handle significantly larger than the minuscule recoil of the ammunition it is designed for, will cause most or all of the handle to separate or break in two places simultaneously, top and bottom of the handle, away from the frame. The largest spring in the gun, by far, is located between the handle and frame. When the handle and frame separate, this spring amplifies this force by a magnitude in a random direction comparable to that of tossing a round of ammunition in a fire. You don't know when its going to pop. You don't know where its going to pop. But when it does pop, you know it is going to be violent and you don't want to be in the way. But at least it cant be as bad as a bullet in the fire. How do I know? Just ask me. I'm happy mine had no ammunition in it when I dropped it.
Happy shooting

It's your control of your trigger finger. There is no safety device on a Rohm revolver.
You let a gunsmith do it.

Inexpensive revolver made in Germany

Don't think Rohm makes any today. They did make a series of inexpensive revolvers of generally low quality.
