Thanks
LM,
I wasn't sure of the Fokker details; I just got lucky with a quick Google Image search on "two-seater executive" and spotted the tip tanks and raked cockpit frames on the first page with a link to Probert, I saw a mention of the S-12 there and after I posted and looked at Richard's post I assumed that it was close enough.
It's Coffeeeeee-time now, but that spelling doesn't mean that it's going to be a long one, so regretfully, it'll have to be another
Open House. Sorry....
With a little luck I hope to have my home internet connection sorted in another month, then I'll be able to do my duty
