Spas 12 Fold stock measurements

[god84]

hi all, after finally giving up on sourcing a TM one i have decided to make one out of a lightweight metal. i've got plenty of metals around the house that with the right tools i could try and make one.

Im asking all the TM spas 12 and fold stock owners to measure everything out, even the spaces between the shell holders.

IF and thats a BIG IF, I get one made and fitted without issues i may make more for those with outone. and with the current state of my job i could do with a de stresser!!

Also people who have tried this before i'd like to know what you did and didnt do, also just general ideas from people would be good too!
