Young Peter and a double drag act

I have posted the first picture previously as an "unknown" photo, but after further sorting I have come up with a couple more that were taken in the same place and very likely at the same time. It could be the garden at Bushey Avenue but I am not certain. The second photo is of "Peter with Jayne from next door, the day of the party". The people in the last photo look like a woman dressed as a man and vice versa. I had wondered if they were Celia and Jack, but wouldn't put money on it. In other photos of the two of them standing side by side, Jack is noticeably taller than Celia. But for the couple here, the difference in height is less pronounced.

Uncle Jack, Aunt Celia and Cousin Peter - miscellaneous photos

Jack, Celia and Peter "Seaforth"

This must have been taken in the late 1940s. Notice the tear down the right side. I haven't found the other half of the picture.

Aunt Celia and cousin Peter

 

Caption on the back reads "On the Lake Naini - when Jack came up on leave. July '42" This is in the foothills of the Himalayas. Peter was born in Naini, according to Wikipedia "a satellite neighborhood and a twin city of Allahabad"

Various "Who's that?"s

Again, sorry they are a bit wonky.

By comparing with other pictures, I have now identified the young lad as my cousin Peter Alan Mackie.

My cousin Peter

He is the son of John Adam Mackie. This is in the back garden at Bushey Avenue, Orpington.
