Thank you chaps! At last something to work with. Some further questions; the grouping of track extensions seem to be in sets of fouror five, looking at the spacing between sets am I correct in saying there are three sets each side? Also, any ideas on where she is and what happened to her? At least now I can get on with my build with some direction. Thanks again! D
An educated guess, rather than firm knowledge, Dodo, but to me your suggestion of three groups of grousers per side looks correct. There are about 19 or 20 links to the top run of track, between the two visible sections of grousers; three such sections, plus three groups of about five grousers (around ten links per group?) would add up to about 90 links per track. The actual figure should be either 89 or 90 (not sure which, although I lean towards 89), so the sums work out.
These groupings have triggered a thought, but I shall start a new thread to ask my questions.
