Leica M4-P black
The camera is in good condition, has some cosmetic wear on the film shutter from being in the camera bag against another camera. The long shutter speeds sound perfectly reasonable, the mechanics work as they should.
M4-P has frames for 28/35/50/75/90/135. The camera was a throwback to the M4 model, and was produced from 1980-1986 after the M5.
