Tim Todd. A Man Out of Time

So i have an old BSA frame up on Craigslist, i received a call about it this afternoon. This is the conversation that ensued…..
Me: hello
Guy: calling about the bike for sale
Me: still have it what do you want to know?
Guy: is it a Harley?
Me: no, says in the ad…its BSA
Guy: whats a BSA
Me: its a British motorcycle.
Guy: kinda like a British Harley?
Me:……………..what?………..no.
Guy: will it fit a harley motor?
Me: no. Its a parallel twin, not a v twin. 
Guy: so a Harley won’t fit in it?
Me:…………………no.
