From the introduction by Weslake500 at YouTube where these live:
Originally shown on Saturday mornings in 1975. Part of the 'Model World' series of modelling programs hosted by Bob Symes. The last three programs of the series were all about model railways.
For those of us of a certain age, these programs hosted by Bob Symes, introduced and opened up the fantastic world of models, and for me personally, model railways.
I therefore consider it selfish to keep the now aging vhs tape of these model railway programs (videoed some almost fifteen years ago), to myself.
These model railway programs along with childhood hero Bob Symes (who id still like to meet) remain personally as fantastic and inspiring today, as they were all them years ago as a child.
I hope you still enjoy them today as much as I still do.
