Trinidad And Tobago National Insurance Stamp Question

I would appreciate any information the forum members can provide on this stamp. I understand it is listed in Barefoot - but I do not have access to that catalog. This is the 13 1/2 x 13 version of this stamp. If someone can give me the Barefoot (or similar catalog) #, value and any additional information, I would be very grateful. Thanks for the help...Greg

If you haven't already read it, there is some information about the stamp here:

Thanks 22 for the response. I spent a LOT of time today 'googling' trying to find out what I could. I read the information on the link you provided earlier today which is actually one of the reasons I asked about the Barefoot info. That site references Barefoot and I was curious what info was in there. The site says there are 2 versions of that stamp and its listing is reversed from Barefoot - so I assume the catalog numbers would be different as well. Just trying to do my diligence in obtaining info. Had never seen that stamp before this week! Thanks for the help!
