Wanted NOS or VGC Ritchey Duro/Racing/Z-max Amberwalls 1.9"

[boy"O"boy]

Hi all.
I'm after a pair of Amberwall Ritchey's for my Ridgeback build please.
Ideally as Freewheel Catalogue spec I'd like a pair of NOS/VGC Duro in a 1.9" flavour. However, given that this may be a long shot, I'd also interested in either Racing or Z-max megabite versions but must be NOS/VGC Amberwalls in a 1.9" width.

I've had the opportunity to try the 2.1" version on my build but unfortunately, they just won't fit....so it has to definitely be the 1.9" type.

Thanks in advance
