Hello Geof,
Don't be too despondent. It is still a nice repro. As has been highlighted on the particular sub-thread the Siam and Brazil vics are probably the most difficult of the official strikes to obtain; in good condition. There are some of the repro's that are very hard to find but as far as official strikes are concerned most people's collection are missing those two.
Having a repro is the next best thing and yours is in good condition, with no edge knocks, defects, dents or verdigris so that in itself is a bonus. It also has the correct to type French produced ribbon.
A nice placeholder until you can get eventually obtain an official strike. Even if you do manage to get an official strike the repro's are handy to use as reference pieces as well.
Regards,
Rob
