Great picture, Gregg. Thanks!

Thats Gregg with his back to the camera for those who haven't met him yet!

A little update- we have the pup engine out and are working on getting it running. The four guns have been dismantled and are being derusted. The de-militarisation done at Brimingham Proof House was very well done... in the barrels a long 1/2 inch wide slot is cut from breech to past the forcing cone but just short of the body housing. When the barrel is installed it is invisible but absolutely prevents the firing of even blanks as there is no support for the casing wall in over 10 % of the arc. A number of other things were done to the breech block and other gubbins but cosmetically they look very good. A fair bit of rust in the lower two guns indicate that they were not under the tarp for some time during its storage.

The next step will be to pull the elevating ram to polish the shaft... don't want rust damaging seals that are still holding oil!

A detailed restoration will probably wait until next year, right now we want it looking passable for the National Aviation Museum Airshow in August.

More photos to follow.
