Ah, maybe not then.
EDIT: Just checked my ebay messages and it seems that they must be the ones that you saw.
The ERTL ones come in at about 15cms, so far too small.
Mason,
There are several sizes of TTE "Bulstrode" I've found..
The 'bath buddy' one I've held & measured is 7.5", quite short & visually too wide, available with or without cargo & a lifeboat.
It is most easily distinguished by having virtually no deck space at all, just a cargo hold.
There is a longer plastic one I've been looking for that's variously listed as 15" or 16", so quite respectable for the beam width.
I believe this to be the starting point for several of the projects on here. It has deck space & cargo hold both.
The wooden "Bulstrode" lists as being 7", and is an odd shape to my eye. I've never actually seen, or measured one.
I'll add that ERTL one to my list as uselessly small.
