Hi Bert,
I noticed!!!  It's my main gripe about Accucraft locos.  It's just so 
obviously wrong.  The first time I saw it was on the S.P. 0-6-0 demo 
model.  I saw the radius rod "up" and expected to see the engine move 
backwards... I was stunned when the throttle was opened and the engine 
went forward.

Aster sometimes omits the port-swapping plate between the cylinder and 
valve chest - probably to save a few bucks - and when they do, the 
return crank is mounted 90* opposite on the crankpin (the USRA Mikado is 
this way... compare it's valve gear layout to an Aster Daylight, which 
has the port swapping plate and consequently has perfect valve gear)...  
Though it's taken years, I've gotten used to the Aster cost-cutting 
compromise.  But the Accucraft error is too blatant for me, if I were to 
buy an Accucraft loco it would immediately require new cylinders (or at 
least a lot of work to them).  I think the combination lever would be 
different, too.

Talking to Accucraft at shows, I have pointed out the errors and simple 
ways of correcting them on future models.  Bing Cheng told me that I was 
the only person who noticed / cared about such petty things, and thus he 
saw no reason to change something that is working for them.  I'm glad to 
see someone else noticed... If more people pointed out the error, maybe 
then they would fix it!

Regards,
Jon
