F-Ribs And Sibs - Inflatable Boat Community

Hi all, thinking of buying this Avon SIB does anyone have any info on this ? model age etc quite like the fact the tubes are Hypalon but unsure about the roll up slatted floor would it be possible to get an air deck floor made ?
Many thanks

@PeterM is well up on the Avon range, hopefully he'll be able to identify the model.
