PRR D16b project: need help finding 68” drivers

Try the UK suppliers

A G5 should have 62 inch drivers I think, not 69.   You might want to check.

Another option is All Nation/General Models stuff.   All of their steamers had 69 inch drivers.   They made kits for 4-4-0, 4-4-2, 2-6-2, 2-6-0, 4-6-2, 4-8-2 and the most famours B&O 4-6-0.   there were also a few Articulated kits made.  

It would take some work to refit them to your mechanism, but that will be true of any other drivers you get.

You might also consider contacting Joe Foehrkolb of Baldwin Forge & Machine.

Fantastic idea, I really look forward to seeing your progress.  My first ideas would be to check the Lionel Mogul, or the Harry Potter Hall-Class 4-6-0.

I had the good fortune to see and ride behind #1223 at Strasburg,  what a great engine. 

Thanks for all the ideas.  I've looked into the Lionel mogul drivers, but the counterweights don't have the same shape (they're curved on the inside, instead of straight).  Same problem, I believe, with the All Nation drivers.  If I'm going to get picky enough to do this, I might as well do it right.

The G5 did indeed have 68" drivers, so those would still be ideal.  I fear I'd have to have them custom-made, but I doubt my operating department has the budget for it...

I looked up the G5 also and I was wrong.   It has 68 inch drivers as you say.   

Stevenson Preservation lines might be another possibility.    And Joe Foehrkolb is a good idea.   he will do the as much of the work or as little as you need.   If you do a lot of the disassembly and assembly, he might not cost that much to machine a set from some blanks.
