Labuan 10 CEMTS

I collected a few Labuan. Noticed this item in my collection a few years ago.I can not remember where I got it from. It was probably part of a mixed bag. It got me excited but unfortunately I have good authority that this is a forgery even though this flaw is probably uncommon. The Labuan Queen's Head stamps are notorious for its forgeries.
Incidentally, I have always considered Labuan to be part of North Borneo/Sabah regardless of  the politics. It is geographically and culturally closer to NB than anywhere else.
Update: I have added a real copy for comparison.The printing is more crisp and is of a deeper shade. The most striking difference is the direction the gaze. In the real stamp, she is looking forwards whereas in the forged stamp she is more looking downwards. There are differences in the chinese scrip on the right. There is a shorter up stroke in the letter N in Labuan. The letter G in postage is less well formed. The 4 rosettes at the corners are also different. The perforations are also ragged

North Borneo 1918 6c with wider surcharge

rare ( stamp on right) as only 1 sheet of 100 printed with surcharge 13mm apart. significantly fewer than the $5 and $10 of which 400 copies existed for each value. probably not reflected in the relative catalogue price. took me quite a few years to obtain my copy but has seen it being offered in recent years by good auction houses.
The stamps of the pictorial issue of 1909 were surcharged and the 2c in excess of its value donated to British Red Cross and the Order of St John. 3 consignments were sent from London and 2 lost at sea due to enemy action.
