Mt. Abu Faint Object Spectrograph and Camera - Pathfinder (MFOSC-P) is animager-spectrograph developed for the Physical Research Laboratory (PRL) 1.2mtelescope at Gurushikhar, Mt. Abu, India. MFOSC-P is based on a focal reducerconcept and provides seeing limited imaging (with a sampling of 3.3 pixels perarc-second) in Bessell's B, V, R, I and narrow-band H-$\alpha$ filters. Theinstrument uses three plane reflection gratings, covering the spectral range of4500-8500$\AA$, with three different resolutions of 500, 1000, and 2000 aroundtheir central wavelengths. MFOSC-P was conceived as a pathfinder instrument fora next-generation instrument on the PRL's 2.5m telescope which is coming up atMt. Abu. The instrument was developed during 2015-2019 and successfullycommissioned on the PRL 1.2m telescope in February 2019. The designedperformance has been verified with laboratory characterization tests and on-skycommissioning observations. Different science programs covering a range ofobjects are being executed with MFOSC-P since then, e.g., spectroscopy ofM-dwarfs, novae $\&$ symbiotic systems, and detection of H-$\alpha$ emission instar-forming regions. MFOSC-P presents a novel design and cost-effective way todevelop a FOSC (Faint Object Spectrograph and Camera) type of instrument on ashorter time-scale of development. The design and development methodologypresented here is most suitable in helping the small aperture telescopecommunity develop such a versatile instrument, thereby diversifying the scienceprograms of such observatories.
