Another BD 5B On the Way

We have not had any report from the recent NZ Warbirds on Parade airshow at Ardmore on 4/6/23.  The airshow sneaked in with the weather and the usual aircraft were displayed including the Warbirds WW 1 collection and several great aerobatic displays were flown.  However one aircraft that was on display in the restoration hangar caught my eye:

This is the BD 5B that has been being built over many years by Peter Sheehan and it looks to be getting towards being finished.  Back in May 1984 it had the registration ZK-TCH reserved and its c/n was AACA/685.  ZK-TCH was used for John Best's Taylor Titch but obviously Peter Sheehan has kept working on it over the intervening 39 years!

In comments to a post I did on BD 5s in New Zealand back in July 2009, the following information was supplied by Peter Lewis and Dave Paull:
