Thanks for posting. It would be very useful to also add pictures of the soundboxes. I'll love to see the Astra and Wild soundboxes. I'll also do some weighing and submit the results.

Thank you Graham for the pictures and info.
Here are my weight results so far.

Expert 4 spring (large) - 3 different weights- 218g, 221g & 227g

EMG 4 spring - 224g

EMG 2 spring (early-51 mm) - 156g

Meltrope III - 142g

I was expecting them all to vary slightly but was surprised that even the mass produced Meltrope III varied by 12g.

Another data point for posterity:
Meltrope III - 148g (includes 10g for the orthophonic isolator)

Notes: rebuilt with white tubing gaskets and the isolator is a Sitko orthophonic.
