volunteer tomato plants

I have loads of these in the garden of our new house.  I've started to care for a few of them and potted them up.  They seem to be doing well with a few flowers.  I have started to remove side shoots.   However, I don't know if they're determinate or indeterminate and know this affects how I should prune them.  Is it possible to know what type they are from their habit?

Could you post some pictures?

I find determinant are much more compact in their growth, and indeterminate climb for the sky.

I have rescued one from a flower bed, but its so far behind the others I doubt it if will produce any fruits before it gets too cold. They are very slow growing.

Thank you for your replies. Not sure if they are growing slowly as I don't have much experience of growing tomatoes, but the largest is over a foot high. They are still growing. i have decided to treat them as indeterminate.
