It takes a little more than just oil to restore such a camera to impeccable functionality. The residues of oil and grease should be removed from the mechanism, sometimes down to the governor where a layman surely is overstrained. I can say that I am a trained mechanician, machinist, and specialist on motion-picture film apparatus having to do with projectors, printers, cameras, viewers, and more since 40 years.
A Filmo 70 which has nothing broken is usually disassembled, cleaned, reassembled, adjusted, and lubricated over four hours. That’d make 360 Swiss Francs with me, about US$370 as of today, net. Afterwards you have a nice instrument with a two years warranty that will run another lifetime. Naturally I check the flange focal distance of each lens port, finder alignment, speeds, upper spindle tension, everything. Sprocket drums can be swapped. The remaining Filmo and Eyemo stocks got sold from Alan Gordon Enterprises to Magna-Tech of Florida last year, so we techs know where to procure parts.
I happen to have a perforator for 16mm strips and I want to acquire tools for it to perforate stock along both edges (2R-3000) as well as Double-Eight (2R-1500). Partnership is invited.
