They seem to have everything locked up in a secret box. I have been buying parts from Mato for conversions and each time, I have inquired about other model parts, specifying M-10, M-3 Medium etc, but have yet to recieve any response at all. With all the sales they have had on the Sherman, it would be fair to assume they would pick up on the business and keep going....but maybe the production bosses are all Chinese or work for Tamiya.
