Re:
Thanks for investigating; I'll measure the frame to estimate the shortest length the box could be.
I have a new frame being delivered early next week which will have a box I can use/trim.
I'll finish stripping the frame today so we can get a package weight too.
Also, sorry for slow response from me, I underestimated how much time I would have to put into cleaning, packaging, getting shipping quotes and taking stuff to the post office/courier.
Kulalez has dibs on the frame whilst I sort a shipping quote
