Full colour pre-printed educational 'Cut and Assemble' model buildings are a cheap and effective way of getting terrain on your tabletop.
I'm a big fan of these. A wide range of historical building types are available at a third of the price commonly sought by the model railway market.
For Winter of '79, I want to bring to your attention two sets by Dover Publications in particular. Unfortunately both are out of print but can be bought second hand at a reasonable price, if you ignore and step past what some book collectors are trying to charge for 'new' copies. These models are HO scale which is slightly smaller than 1/76th. Don't worry though, it's a positive as the models fall between 20mm and 15mm scales so unless you are a fussy bugger, can be used with both.
South Downs Way.
The 48 page set includes a village church, pub, post office and 5 other houses, plus walls and other village paraphanelia to make up the '12 Buildings and Structures'.
I picked up my copy in a book clearance for around £2/$3. Dog-eared at the corners but didn't effect any of the buildings.
To complement the English Village, Dover also published Cut & Assemble an Old Irish Village (Edmund V Gillon Jr, 1991). This has 5 buildings and a renaissance tower. It reminds me of villages on the road to Braemar, so could equally be used in a Scottish setting. Available second-hand for around £7/$10 - bargain.
You could extend both sets with maybe a download and print or Superquick (etc) card country garage, school or maybe some more modern detached houses.
