The rear SR hub is on solid axle and spaced at 120.However the bike they were built for had a bolt on gear hanger so I used an extra long axle. The axle is 160 total.Nuts fully flush would take up 20mm of that leaving you enough for a 130 mm spacing plus 10mm to allow for the two dropouts.Would only be a matter of washering and redishing.I bought the hubs new old stock and they have done well under 50 miles and are butter smooth.The rims I aquired a good few years ago and as said I think they are rigida. They are not marked with a manufacturers stamp.They are fairly narrow section with sound brake tracks all in silver.They were for a jrj but I could not get on with it so stripped it and sold most of the bits off.If you are interested you could have them for £45.00 plus carriage.Would supply photos if you want them
