Hi,
I have LHD and to be honest - not an issue (I also drive a RHD auto car, and manual RHD so mixing it up doesn't cause me issues)
Just some quick thoughts:
It's listed as 1971 - so upgrade to disc brakes is strange as it should already have them fitted
The arial - thought 1971 was a single mount not double
With the above in mind...is it a 1971 bus? Doesn't have the usual things - could be an early one so I'd ask if it's got a brake servo fitted (should have if 1971) and ask for the m-plate code to de-code it and check the age
was white over gray a standard colour? if not it looks like it's already had a paint job so what could be hiding underneath....also buddy seat and cooler unit is missing so add a further £400 - £500 to source good ones to complete - also doesn't have original panel cards in rear so again, looks like it's had work and isn't exactly an OG unmolested example
Just initial thoughts from looking at piccies - I'd get m-plate code and make sure it's firstly a genuine westy, and secondly it's definitely a 1971
hope that helps
