Though tactically omitting the name of the ship for security reasons, this was in fact for the Ship's Company of HMS Frobisher, which was engaged in convoy duties at the time and was at Simonstown after a short refit. 

Metre rule measurements as best I can, please see pictures.

Where I have provided no additional information on the item it is because I can find no identifying features to suggest where it has come from or what was the original format.

In condition shown, please see photos provided as best description, zoom is enabled for best viewing. 
Always happy to provide additional if requested.

I post all paper items protected and in proper card backed envelopes. 

If I have quoted a parcel postage price it is because I can't send it flat any other way without adding new folds, which I won't do.

I will combine postage when I can, please request an invoice from me if UK buyer.

If non-UK, I only ship internationally using GSP, they will provide you with a combined postage invoice, but can't do so after a payment has already been made. Please await their invoice if you want combined shipping.
