I've been asked to make a few of my chamonix extension brackets for the 45n-1 & 45n-2. Constructed of 9-ply baltic birch, approximately 8 1/2" long x 2 1/8" wide and increases the cameras extension by approximately 5". That's more than enough for a 450mm or a 250mm in 1:1 territory. Can be mounted anywhere along the focusing track. $75 shipped worldwide. Payment by paypal or postal money order. PM me for payment info.
A new batch is ready for shipment. I've decided not to add the grey paint strip to the top but added engraved lines instead to aid in front standard alignment.
