just wanted to make you aware of a company i have now used several times, macs mouldings,
i have no connection with this business other than being a happy customer.. but check out the quality resin fittings and mouldings- generally at larger scales, - notice they also do larger scale items for garden railways and stuff for model tanks and trucks
there latest additions are lifeboat style window frames.. .they are fantastic.......
