Nick Acton has a reproduction bleeder tool and the tool roll (I think). The spanners (wrenches) aren't all that rare and can be found separately or in sets often on eBay. Thor #2 hammers are still made though vintage ones show from time to time, also on eBay. An original BDS Engineers screwdriver is in the realm of unobtainium. Your best bet if time and/or money are any consideration is a vintage Stanley screwdriver. The shape is similar and can be painted in similar fashion to the BDS.
Don't forget the Shelley Jack, Tommy Bar and handles as well! All are getting rare and going up in price quickly! Nick does have a reproduction jack and I think handles as well.
