Clocks, Watches/Pendulum feather spring


I have a Welby 8-Day Westminster Chime chain wind Grandmother clock. It was purchased in 1975 for my Grandparents. The feather pendulum spring is breaking and the pendulum wont swing. The movement is stamped "74" which I believe indicates the year it was built. It also has a number: 451-053 and 85CM 70.77. Can you direct me to where I can purchase a feather pendulum spring? Perhaps you can sell me one? My interest in getting it fixed is sentimental as it was my grandparents. I realize it does not have significant value as a clock. Please advise.
Thank you,

you need a "Hermle suspension spring for a 451-053"  they cost me $1.50
they can be had at any clock repair facility or on line (there would be mark-up of course)

this is what was used in 1974 (newer clocks had larger):
