Am pretty sure that these are spring plates for an old horse drawn sulky. 8 plates – 4 tops & 4 bottoms. All plates are slightly rusty but nothing drastic that would prevent them from being used. One still has the original centrebolt. Minor wear/damage but nothing drastic. Squareish plates measure 56 x 54. Holes are 37 & 40. 10 thick. Ones with tabs & square holes measure 106 x 66 x 12 thick. All dimensions in mm & approx. Need a good wire brushing. Need to know something else??? Pls email. Price includes post anywhere in Aus. Pls check out my other items for sale. You won’t believe the variety. If it is still listed, it is still available. Pls note – location is Ellalong NOT Ettalong.
