Established in 1903 under the name of the Stirlingshire Stove & Iron Co Ltd, making stoves and ranges. The four partners were Andrew Gracie, William Gracie, Alexander Brown Harley and William Leslie. In 1922 the Stirlingshire Iron Co went into liquidation and the works were put up for sale. In that year a new company was formed at the Camp Foundry in Motherwell, called the Broomside Co (1922) Ltd. The partnership was formed from Robert Smith Anderson of Polmont (550 shares at £1 each), Andrew Auld of Stirling (400 shares) and Alexander C Anderson (200 shares). Shortly thereafter, in December 1922, they purchased the Bonnyside Foundry from the liquidators for the upset price of £1,500 and transferred their registered office to that address. £200 worth of repairs were undertaken immediately, and the following year the Camp Foundry was sold. More capital was required and Andrew Auld increased his shares by 1,700, William Smith Anderson acquired 150 shares, and John Smith Anderson 150. The following year they wer joined by Robert Turnbull with 500 shares, Donald Cameron 200, Jean Morrison 200, Alexander Mitchell Duncan Ferguson 100, Thomas Neilson 50, and Edmund Logan 200. Robert S Anderson was appointed Managing Director, and the firm concentrated upon the production of ranges and stoves. The 1920s were not and auspicious time to start a foundry as their was a general depression in trade. In 1927 new lavatories were required by the Sanitary Authorities, and suction plant was installed the following year to extract carbarundum dust from the grinding shop as necessitated by the Factory Act Amended Regulations 1925. The contractor for this was A & J Main, at a cost of £220. To cover these additional expenses Andrew Auld purchased another 1,000 shares. In 1929 the company extended their products by making cinima/theatre chair standards which sold well. To stay competetive output had to be increased and more land was acquired to the east. 1930 also saw the works convert to electricity, at a cost of £394 - the old steam plant was obsolete. W S Anderson died and his shares were transferred to his wife Daisy Anderson. By 1932 the depression had become very deep and Andrew Auld tried to sell 2,600 of his shares for only 1s each to the company. They refused and the shares were transferred to his son, Andrew Bisset Auld. In 1933 the company bought Ashbank House in Polmont from David Robertson for £250 for the Managing Director. A new product, the Beta Combination Grate, was introduced which required the building of a new kiln for Berlin Blacking. This together with new offices cost £500. A new bay was also added to the moulding shop for c£450. The following year a £500 warehouse was built. In 1935 RS Anderson, the Managing Director, started to receive unissued shares as bonus payments for productivity. Andrew Auld resigned due to ill health in 1936 and his son became a director. Alexander C Anderson died, his shares being transferred to Elizabeth Inglis Anderson. New buildings were added to the fitting dept. The moulding shop was extended the following year by Jas Menzies & Sons for £650. 1938 also saw the introduction of summer holiday pay for the workers, and the directors started to receive fees in 1939. Elizabeth Anderson, the MD's wife, purchased 100 shares in her own name. The foundry intially struggled with the restrictions caused by the Second World War. In 1940 they purchased defence bonds which they sold as the war progressed. ED Logan sold 200 shares to Robert Murray Hudson at £1 each. As the domestic market had been practically extinguished the company switched to general engineering work and machine tool castings. War Dept heating stoves were made. 1942 saw EJ Anderon sell her 150 shares to A Ferguson. In 1943 they joined the Domestic Fuels & Appliances Committee and the Combustion Appliance Makers' Assoc. Daisy Anderson sold 150 shares to A Ferguson at cost. 1944, D Cameron died and his shares were transferred to his daughter Jean Beaumount. Towards the end of the war, in 1945, it was decided to rebuild the fitting shop at a cost of £2,000 with a further £1,000 set aside for fittings. Ministry of Works approval had to be obtained. The momentous decision to join the National Light Castings Ironfounders Federation was taken in 1947. Investment continued and in 1949 the moulding shop and cupula were reconstructed. The works finally closed in 1995.
