Nice theme,,Wales,,
Window "bombs" were the cast iron weights hanging as counter-balances in the side frames of the old Windows,
As soon as our "friends & neighbours" had gone, left house(slum clearance days) then WE wuz in,, lol
Window weights (bombs) 1st Tat,, then 2nd the Lead pipe under the sink,,
Chopped at floor level & bent over with a brick, (Quieter than a hammer ) Left no leaks so no complaints etc,,
Then the wiring stripped out of every place (After Elecs isolated,, i did that age 8 lol )Dad a Sparkie,,
Burnt the wire on the Bomb peck,, then run all of our Glory hoard to Kirby,s yard,, Good price & clip round the ear..
Best "tatters" gang of kids on Summer Lane,,, Yo JohnY
