Here we have two dealers service charts / wall posters showing an exploded drawing of an engine for a BSA Bantam D10 175cc motorcycle and sprockets / gear ratios for various BSA motorcycles (C10,C11,C15,B32,B40,M20,M21 etc).
They are well used and in poor condition.
This would be ideal for a BSA motorcycle collector and enthusiast.
I have other BSA service charts similar to this one so please take a look at my other items.
