Clavioline Sound synthesis

Hello again, here I go on another sonic journey. After watching ‘Bright Sparks’ documentary-particularly the Freeman String synthesiser section, he mentioned he was in a band playing the Clavioline through vibrato and Watkins Copycat delay unit. I have assembled a ‘very rough’ patch based on square waves, vibrator, Vacuumba tube distortion, Chorus and Chronoblob. Am I going in the right direction, not sure? Any advice would be very welcome. I’ll put the patch in Patchstorage so you wonderful people can have a look. Thanks for your time.
