Has anybody here heard of VW aeroconversions by a company
called metric A/P? Any experiences good or bad?

I haven't been able to find them on the Web.

...

Never heard of him...

How big is this company?

I have yet to find evidence that they exist. Consequently,
speculation as to their size would be unwarranted.

According to Bradley Aerospace the engine included with the kit
they have up for auction on eBay is a 1600 cc VW aeroconversion
made by metric A/P.

...

I dunno, Fred.

I wrote to Bradley Aerospace saying that I could not find any
information on metric A/P, and aksed if they could refer me to
a website or at least give me their location, as in city, state, or
country.

Here is BA's reply:

"Metric A/p They have been building my engines for 12 years.
Thank you"

That's it. Why would anyone bother to reply to a request for
information, without providing any information?

It boggles the mind.
