hi Norry you will like the (TUG500) thats what i call it lots of fun .I noticed the plug on the floor at Lawrie and Jackies place when we had a visit earlier this year and got him to run one through the vac former .
Mine has twin screw with conventional rudders and at the moment a home made wheel house ,but i have the vac wheel houae to build yet.
Lawrie mentioned to me about starting a collection of tug's for steering fun as he has a plug for barges to go with the tug's but i have'nt had time yet as i am building the latest model DUTCH courage RIVER, and it's taking all my time along with xmas and work .
This is the original at Model Slipway including the dust.
