A few quick points:
You should break up numbers over 999 with commas, eg:
This does not of course apply to years, eg what I assume to be the year 1951.
Do not use full stops or periods instead of commas in English. They are reserved for indicating decimals. For example, in English 6.500 means six and a half, NOT six thousand five hundred.
You have used L (for liters or litres, I presume) but you have used kg for kilograms. You should be consistent. I suggest you use lowercase for both (l, kg). Now you may see why it's important to break up the large numbers with commas:
30000l (could be seen as 300001 - three hundred thousand and one)
30,000l (this can only be thirty thousand)
N/A means Not Applicable so this means you consider the question to be irrelevant in this case. This is normal usage in appropriate circumstances.
For Remarks, you would normally write None instead of NIL.
