First problem is that 8F12 is attributed to be a Thulin D. It is not! It in fact is a Gourdou-Leseurre GL.22C.1 that sits close to it on the floor of the museum at Tikkakoski.
Second problem is that the existing aircraft profile with the correct aircraft type tail no 8F.12 can not be found by entering the registration into the search tail no form.
You always get this error code "404 Sorry! Cannot seem to find the page you were looking for."
The profile can however be found by searching for "Gourdou" as manufacturer. When clicking on the link at the tail no, the same error code appears.
It is however possible, to link new photos to this profile. I just did that and the photo can be seen as thumbnail and viewed in full size via my gallery at the Museums / Finland /Tikkakoski folder.
Possible solutions:
1 Change the profile with tail number 8F12 to the correct aircraft manufacturer, type etc, eliminate the false link to "UNKNOWN" and relink the photos from 8F.12 to this profile.
2 Delete the profile with tail number 8F12 and change the tail number of the profile with tail number 8F.12 to 8F12.
3 Delete the profile with tail number 8F12 and find some way to overcome the problems searching for tail number 8F.12.
4 Maybe there are other solutions that I did not think of.
Please let me know as soon as any solution can be applied.
Best regards
