David we've discussed this privately but I can't remember the outcome...
I have, with your permission, copied over quite a few of your pics to the gallery, but by no means all. If you can work out which ones I don't have and email me over the pics, I'd be very glad to fill in the gaps.
Alternatively, if you want to build a separate Troubledshooter site within the gallery yourself, you'd be very welcome to use the gallery's pic host.
Please let me know if I can help to preserve your superb work to document so many rare airguns and associated documentation.
