Well done! OM-1n is my main shooter along with OM-2. Agree that a CLA and conversion to take SR44 cells is a good investment. If you don't know already, the foam on OMs goes icky just like on all other cameras and while the foam in the film door and mirror buffers is easy to replace, there was also a wedge of foam under the top cover over the prism which degrades and irreparably takes the silvering off the prism. Shows up as blotches usually along the bottom edge of the view finder. Fortunately the prisms are the same as the (cheap) OM10 so not too big a deal to sort if yours is already bad. If not, and still looks good, but the door/mirror foams are sticky, I wouldn't hang around too long............
