I acquired this stamp, Guadeloupe Yvert no. 32 - 1892 Shipping&Trade 15 c blue. Actually it's a double for me, I was about to put in my 'for sale' album, then I noted the actual content of the cancel.

Judging from the partly visible location '..t-bourg' I determined this must be 'petit-bourg'. The name on top I assume 'Guadeloupe'.
But the date seems odd to me. When reading the cancel with 'Petit-bourg' at the bottom, the date would read '17 RVEF 99' (with letters 'RVEF' upside down)
When flipping the image the month becomes clear: FEVR ... so 17 february 1899.

Has anybody seen this before? Details appreciated ...
