Gt40 chassis identification

[Luck]

Hello everybody, I'm a new member and I'm looking for help in order to identify a GT40 chassis. In 2005 I bought a GT40 MK I with old version of FIA Historic papers. This car was "supposed" to be rebuild in South Africa from the famous scraped chassis 111 (Bondurant/Withmore at the targa). I didn't buy (nor pay !) the car as if it was the real 111 but thanks to FIA papers I participated to many FIA races in Belgium and in france. In order to comply with the new FIA HTP regulations, the car was completely rebuild last year and presented to FIA this winter in order to get the HTP papers. The car is considered 100% in compliance by the FIA representative BUT the FIA ask me to "only" give the chassis identification means manufacturer in order to get my HTP ! we'll see but at least I could be a step ahead...... Can someone help me ? I join some photos of the chassis during restoration but I have a lot more!! Many thanks in advance
