Hi

Olive Drab paint code is BS381C 298

Olive drab from different suppliers does come out slightly different colours, there will also be slight variations in colour depending how the paint is applied brush/spray. The colour also changes with age.

I use a semi-gloss from Express Paints in Portsmouth

The only other recommendation I would make is buy sufficient paint to do the whole job

Hope this helps

Cheers
