Vintage Rogers (Arbiter) Clockface Snare drum throw off

Rogers vintage throw off. Some blemishes and marks from use. It's from an Arbiter drum so the throw off was adapted to fit that in the factory. The original holes are there and threaded so it's going to work fine but will need the front unscrewed to remove the fixing bolt in the middle. 

If it's not going onto an Arbiter then a new fixing screw will be required.
