Richard,
Just after purchasing the Nutshell I also bought a Raleigh hence understanding all the differences. In the end I decided to restore (with my father's assistance - he was trained as a cabinet-maker) the Nutshell and sell on the Raleigh - I cannot remember who to.
I've used the Nutshell on some very cold nights (it is very cosy) and took it to some distant events as well as simply using it to go on holiday.
They tow exceedingly well (the wheels are set quite far back) and are surprisingly practical. All the seat cushion, bedding and most of the camping equipment will fit inside.
What did the Raleigh fetch on ebay and what condition was it in?
Kind regards,
Colin
