The HEDSON Revolving Drum Multiplier is a look a like of the Unique Taylor fishing reel, the first Australian revolving drum multiplier reel designed and made in Sydney in the mid 1930s by R.R. Taylor Repetition Engineers Pty. Ltd. The maker of the Hedson (c.1949) is not known, but it is clear that the maker took advantage of the fact that the Unique Taylor design was not patent protected.

Only a limited number of HEDSON reels were produced. These included: (H1) Hedson All Purpose model; (H2) Model No.100, Hedson Super Cast with the plastic revolving drum with Hedson name moulded in the spool; (H3) Hedson Standard with aluminum alloy body and spool  (H4) Hedson Deluxe version with the body, spool and gearing cover, machined from Aluminum alloy Bar Stock; and (H5) Hedson anodised silver aluminium alloy model. HEDSON fishing reels were produced with two different main spindle bearing options, ball bearing or sleeve (bush) bearings. The multiplying models came with machine cut gears; check lever; non-go back lever-prevent crank handle reversing; free spool lever for casting with automatic re-engagement of gears upon crank movement. According to Craig Aitken, Fishing Tackle Guide, 1949, a non-multiplier HEDSON, Model No.101 was produced, with direct-wind, un-geared version with check only.
