Welcome to the Strelets Forum. Please feel free to discuss any aspect of 1/72 scale plastic figures, not simply Strelets. If you have any questions about our products then we will answer them here.
I doubt anyone here knows much about casting tin soldiers (including myself) but I do enjoy some 30mm flats. Super cool to see other people that are into that side of the toy soldiering hobby. Sorry we couldn’t help, but I hope you find the information you are looking for Jesse!
