I don't mind international Ebay purchases, you just need to read between the lines with Ebay descriptions with any purchase.
Fitting the TP shutter to the MPP MkVIII is a bit more difficult than I thought, the depth of the shutter box is greater than the space between the bottom and top clips for the lens board. So it would have to stand off with a gap (which it would anyway to accomodate the shutter speed dial), so I need to make a custom lens board and/or get a board with a bigger hole in it than the Copal #1 size to stop possible vignetting. Otherwise some double sided tape would have done the trick to mount the TP shutter on the MPP Copal #1 board. Just a thought but would a Copal Press #1 shutter work? They seem to be cheap and you can get them without an iris.
