This car surfaced for sale in the US. It is an early car, chassis 177458, and the former CZ 3705 has the same knife-edged scuttle/dash top as we discussed here.
The car is shown here in Pensylvania.
If anyone is close by, please go and find the body number on the transmission tunnel, and find out what the hood looks like. This car also has the same sidescreen retainers as the early Boorman car and this could support that they were fitted from new.
NOTE: several people are searching for original cars so make contact if you have something tatty sitting in your shed that needs restoration or attention!
