I hope the talk and any others can be preserved on good quality video for posterity, and possibly on YouTbe, etc. if speaker is agreeable to this.
Even if it can’t be published on say YouTbe, it would still be valuable to video it and give the video to the speaker for him to keep, and use as he sees fit.

Yes, I would join.

On another unrelated site the current owner of the Walrus project posted in December 2014 that he was progressing slowly but doesn’t have an end date yet. Over the past two years they have made progress, and have a fuselage and undercart, the core of an engine and are just about to complete the tailplane. Whilst they have a lot of fixtures and fittings, but are looking for the other major structure (e.g., wings, engine pylon and nacelle). He asked for any leads on Walrus parts anyone has knowledge of.
