The SINGER`S were and are an Amazing car and Great Value, The only thing I can remember is to watch that Gear box, they were prone to go and a bugger to replace, same as the IMP. I can remember going to race meets just to watch these, Boy did they go !!! nearly all put 5.5 RSJ`s ( think that`s what they were called ) arched wheels on them to give them better handling, and the tiny hand crafted wooden steering wheels they had ?? Fantastic !! they used to put acetone in the fuel mixed to give way more power. I`m assuming you`ve changed the Dynamo for an Alternator or be it done before you got it ? and the Points, they were a bugger, always going along with the plugs,1965 was the change towards the Electrics, I can remember one of these cars running on a 6 volt battery, this was all changed of course, these little babies woke up the Mini`s when racing, Love em !!
Oh and these Beauties used to race with 2 x Twin choked Webbers , same as the mini`s did ?? Bloody fast
