Hi Kuba, nice to here from you again.
I remember when you collected the body you bravely produced an angle grinder and set about cutting it down so it would fit into the back of your van!!!
I was a little worried at the time but wow, what an effort!!!
What you are building is a unique effort as never before has one of these been assembled and IMHO you are doing a fantastic job !!
Only 3 of these bodies have been moulded, your's, one that was used as the Alpha prototype and one is hanging from the ceiling in my workshop (awaiting inspiration).
Keep the up-dates coming and again well done!
