Apologies for the non-CCP4 related question, but this is the best place to look 
for an answer.

My puck is stuck in a shipping dewar after a "freak" incident. I was tilting 
the dewar to pour the excess liquid nitrogen out before shipping. The puck 
holder slipped partly off the dewar and hit the side of the large container in 
which the liquid nitrogen was discarded. The impact made the T-shaped rod that 
holds the puck in place slid out. This has happened to me before and I just 
turn the dewar upright and slide the rod back in place. But this time the puck 
- not locked in place by the rod - slid as well. It is not possible to thread 
the rod through the puck hole, nor it is possible to get the puck holder out 
because the puck being offset hits the dewar neck when trying to take the 
holder out.

It looks at this point as both crystals, puck, puck holder and shipper are lost.

But maybe not! Has anybody had this issue before and how was it solved?

Thank you in advance for your help.
