I finished this snare this week ---
Pre-war Windsor brass shell, original lugs and rods, strainer and butt plate. I raised the lugs on rubber washers so modern heads/hoops could be used. Sadly, the shell has a diameter of 13 1/2", I have a new calf batter head but no flesh hoop to have a snare side head made. I tried a couple of heads from 50's Olympic snare shells, but they were around 13 3/4" diameter. The conversion was pretty straightforward, adding the washers to lift the lugs but finding long imperial mount screws took some digging. The strainer is a bit flimsy, but it works with a bit Heath Robinson knottage.
It's very bright, quite a lot of 'ring' and has a distinctive 'vintagey' timbre but still has a modern tone - fab rim shots!
