The Ikonta has a Compur shutter. I have three 50+ year old Compurs on my Linhof outfit, three more Compounds with old Dagors mounted in them - the newest is 1925 or so, the oldest about 1908. Rolleiflex Standard, Compur, 70+ years old. Other cameras with mechanical shutters, Nikons 40-45 years old, all have been serviced with appropriate cold weather oil (supposedly good to -75f). All are utterly reliable in subzero f. temperatures.
Why do mine work reliably and the OP's do not??
Shall I request cold weather oil for the rebuild?
