Want to Buy WTB: Lens standard from 4x5 Speed or Graphic View

hello,

I'm looking for a lens standard (just the part that holds the lens board) from a 4x5 Speed or Graphic View. That's the standard that takes 4"sq lens boards. If you have lens boards to go with it, even better.

Postage would be to Montreal, QC, Canada, H4A 2R2

Best Regards,
Bogdan

OK, found what I needed. Thanks!
