43 years spreading now, but wooden derby thats a blast from the past, as a 15 yo apprentice was giving half a plasterers tool kit, the rest I had to buy out of my £5 per week pay, and yes a wooden derby, wooden rubbing up float,( for browning) wooden crossgrain float for skimming (used on angles) 2 wooden st edges, wooden hand board, a wooden square for reveals, and a wooden tool box, tiling gear, a Ragni plastering trowel for floating, a Tyzack for skimming, a rounded gauger, a square angle trowel, those big blue tin snips, you can still buy them now, different small tools. and long tools, to get in akward places,and more.
those days you worked in a squad, and it was mostly float/set, so as an apprentice you would be straight on the tools, and you learned quick, I was still 15 when the building trade went on strike, and was told the apprentices had to work through, and as the only app plasterer I had to float and skim a double off shot out, with the 15 yo app joiner mixing up, proud as punch when I finished it, the boss was delighted with the job, and said there will be a little extra in you pay this week,true to his word £1 bonus.
