Charlie asked me to eventually show you the ACE he mentioned but already wrapped away. Glad to help here - and of course I had followed this thread VERY closely before being PM'ed by Charlie.
I share some of Mike's thoughts and would certainly like to build something like the "Eierlegende Wollmilchsau" (<= German for the "unreachable, universal, all together, never dulling gadget) :D
Unfortunately my collection is not that good as some of you might think it is. So I had to cheat a little to show you the head Charlie is most likely speaking of.
I took the pictures from Wade Phillips "book" (2. Ed., page A-27), together with a ACE "Jet 4-bld" with 1.7" bleeder in it. The "Alaskin 4" (solid and vented) is on the right and this will be the head Charlie is refering to, am I right?!
Notice that the "African 4" (left) was slotted to take a Bear auxillary blade! Also notice, that this head is ABCC
#0001 with ACE bleeder!
As I am lacking the old Alaskin I'll show you the very similar "Super-X-Press" and the 1.7" ACE bleeder in side view. A slightly larger (1.9") ACE bleeder was also available (see pics). For comparison see a 1956 Bear Razorhead with chrome bleeder
I am off now for some hours but will certainly check again.
Cheers, Falk
