"With reference to Mr. Crow's article in Bulletin No. 12, I have a cover written by Mrs. Alice North 'Gibraltar Camp No. 34, Kingston Jamaica.' and addressed to a Mr. James H. North '39 Castle Ramp Gibraltar.' On the obverse is a l/- Jamaican stamp cancelled Kingston cds. 21 Jy. 41. In addition there are two strikes of a black 35mm. double circle (circles 1mm. apart) cds. that has at top 'Gibraltar' and at bottom 'Camp' in sans serif letters and are undated. On the reverse is Gibraltar arrival stamp 12 Aug. 41.
My first day cover with purple TRDS Type 37 dated 1 April 1942 (not 1941 as stated by Mr. Crow) is an O.H.M.S. and 'Official Free' envelope and bears on the obverse, besides the Gibraltar TRDS Type 37 a Kingston cds. of the same date and one strike of the black 35rnin. stamp referred to in my above cover (undated). The cover is addressed to Kingston and bears on the reverse a Lascelles cds. and a Kingston arrival stamp of the same date I April.
Now, this black undated mark was in use some nine months before the Type 37, which appeared when P.O. was officially recognised and given a TRDS. Therefore the 35 mm. mark must be that of the Camp's Military P.O. as it is undated and not used to cancel the stamp. Such mail must have then been sent to the nearest convenient P.O. for cancelling. Even when honoured with a TRDS the military could not give up the use of their camp stamp. Perhaps this mark is new to Mr. Crow, as the straightline type he mentions is new to me. I hope he has it on dated cover? I do not know just when the camp started, but obviously long before they got even a TRDS. My Birmingham 2 cds. is on a single stamp off cover dated 10 Nov. 43."
