Steve, 

My "complete" 10 kVA, 14,400 volt pig (complete meaning 
the transformer in the tank, w/bushings and oil-filled since that's 
the way that they are normally obtained) weighs about 280 lbs.. 
I would only be guessing to comment on how much just the 
"guts" weigh, but I would dare say that the bare, open-core transfor- 
mer inside comprises at least 50% of the total weight of the unit? 
It would really depend on the type and build of the tank assembly. 

I believe the tanks may comprise a higher percentage of the total 
weight of the trannies in European countries as opposed to the US, 
since the external tank housing of pigs in the UK looks to be much 
heavier and boxier than those of US pigs. I remember seeing the 
webpage of a UK coiler that obtained a 5 kVA, 11kV pole pig and 
the complete unit weighed like 370 lbs! He then took out the guts 
and placed them in his own custom tank, with the required oil to 
fill his smaller custom tank and it ended up weighing less than 200 
lbs, if my memory serves me correctly. Sorry, i can't recall which 
coiler that was :-( I believe The Geek Group obtained a complete 
oil-filled tank 10 kVA pig that only weighed in at around 208 lbs, 
but most complete 10 kVA pigs tip the scales in the 250 to 300 
lb. range here in the US.
