Just got a Ric bass in my workshop and I'm struggling to identify it as the serials have been removed. The owner believes its a 1964 RM but looking at photos on the web I'm not convinced - this one has silver top knobs and all the screws for the pickguard and pickup are slot heads. All the photos I have seen of 64 RM's have black knobs and cross-head screws. Pic here https://twitter.com/ChriscxdDale/status ... 6926922752

Can anyone shed any light on the model and year?
