Downdraft SU carbs

It's my first attempt at refurbing SU downdafts. I note that mine don't have a damper piston but do have the spring in the dash pot. Is this correct?

Thanks
John

To answer my own question.

I've been in touch with SU carbs in Salisbury and they confirmed that the downdraft carb on my 1936 14 shouldn't have a damper piston but should have have a spring.
