** I bet you enjoy causing road rage and holding up traffic with that 20hp 
hot rod. Great brakes also.

** My 26 T coupe sits on boxed 28 rails with Model A fenders. Henry designed 
the A frame that way since the 28 A body wasnt ready until March and 27T 
bodies were used.  It has a dropped front axle with 59 Buick finned aluminum 
brakes, a 65 Mustang rear. It rides on 1935 Ford wire wheels and radials. 
Powered by a supercharged Ford flathead V-8 and a beefed Ford C4 
transmission. The Corvair steering box is another deviation from Ford but it 
is a perfect fit.

It travels anywhere I want which has included a few over 1000 mile round 
trips at highway speeds. Strictly a single occupant vehicle. Passing power 
is incredible as is its 1/4 mile times.

** I guess you dont have the interest or ability to try for a CW DXCC with 
them.
I went back several years before WW2 and built a PP-211 TPTG for 80M. 
Receivers were all 30's era including a 1934 National FB-XA and a 1931 Scott 
AW-12. It took me 2 1/2 years to confirm DXCC on 80 CW.

The current project is a 160-20M TX with all pre 1930 tubes and a 860 final. 
The receiver is a 1928 Radiola 60 superhet that was given to me in pieces 
with no cabinet, and the ham band converter is based around correct era 
tubes and components.I expect to work DXCC with that on all bands.

After that a Class B modulator, an early 30's development, using those same 
211's will be added and my fully restored 1935 first run HRO will join it 
for some more fun and hopefully a 20M AM DXCC.

Would you care to join in one of the above efforts? Many others have been 
doing it for decades and Im still a relative newcomer.

** And maybe long in the dumpster or seriously modified since AM will have 
been banned and only digital modes (including a SSB version) in use.

** Along with most equipment relying on B+ level components. Most of the 
younger generation could care less about our old crap.
