Supermarine Scimitar

Good Day Gentlemen!

In order to complete a modelling project, I am trying to understand how you could access the 2 RR Avon engine from the SCIMITAR top fuselage.

Many drawings show 2 large cowlings, others show 4 cowlings. From pics it is difficult to understand if the cowlings split at centerline or not.

Any help appreciated.

Thank you
