I am sending a '43 Ingliss Mk. II parts kit out to get built into a semi and have come across 2 tripods and would like to know how and where they are marked ? I also would like a approximate value as I do not have a clue nor does the fellow who has them and as he is a very good friend and does not remember what he paid I'd like to be fair. The tripods have the 2 straight legs and the single extendable one. I appreciate you help. Thanks, John.
