Hello Hanjo
For fenders (mudguards) try Renovation Spares, 49 Feckenham Road, Headless Cross, Redditch, UK, B97 5AS. Tel 01527 543796. They should have Scott pattern mudguards in stock but will manufacture ones to dimensions and photographs if necessary including valances and so on if needed. I think your mudguards should not have valsnces.
For handlebars try Armour Motor Products (Bournemouth) Limited, 784 Wimbourne Road,Moordown, Bournemouth BH9 2HS Tel 01202 519409, http://www.armoursltd.co.uk. There is a down-load of the catalogue available as it is often difficult to get through by telephone. Armours make a number of styles of handlebar in either 1 inch or 7/8 inch diameter unfinished or chromed. I do not know whether you need 1 inch or 7/8 for 1936 or whether they should be chromed or black like earlier bikes. (I would like to know if anyone can enlighten me). I have used what are referred to as Norton touring style (I think).
Armours will also do passable (but not strictly correct) handlebar controls and levers. If anyone knows of a decent source of handlebar controls I would like to know.
Armours also do a saddle type seat, again passable but not strictly correct. You might find a period saddle for sale on ebay.
I think that the Owners Club offer the side castings for a rear stand. If not try Tim Sharp, 14 Hazel Beck, Cottingley Bridge, Bingley, West Yorkshire, BD16 1LZ.
Good luck with the rebuild !
