what does this fit?

[Richard Coutts-Smith]

Thanks Derek,
Thats a big Mortar. Did not realise barrel length was anything like that. Does fit though as one of the sets of mounting legs was substatially bigger than the others.
As for selling, I think the postage costs would kill that idea. Quite happy to hang on to it now I know what it is, (although the chance of getting another set of legs to match it are now remote.), it can go up on the shed wall for all to see.....that'll be me, the dog and two possums!
Regards
Rich.
