A tall bird from Paddington
GWR Goods depot crane
I couldn't find any drawings, so the dimensions are guesstimates based on photos. The build was a real pleasure, especially sourcing the parts.
I'll let the pictures explain the rest - gradually!
In other words, a shed crane. I still need to model the operating lever which was situated next to the crane, and which (as far as I understand) connected to a mechanism beneath the deck. I plan to build at least one more of these - although possibly a more heavy duty type.
There are a couple of things I might do differently on the next one. I think the counter-weight is a little underscale. I will also do the pulley wheels different next time. We live and learn!
PS: Thanks to Missy for the tip about the watchmaker's parts, available on ebay.
