Working tool (11) Victorian - Sewing set and patent

Lotto da Collezione Sartoria Milanese – Tools in Fine Bone from the 1800s, Compasso "Michelhaus" Patented with Original Box and Rare Hand Embroidery Manuals from the 1920s/1930s
Exceptional and cohesive collectible lot themed on vintage tailoring and premier haberdashery, entirely tied to the Milan commercial and manufacturing district at the turn of two centuries. The lot stands out for the rarity of the paper pieces combined with their exact original mechanical components.
The lot includes:
1. Cutting compass / adjustable shear in highly precision polished steel. On the cursore there are the engravings "OSCAR MICHELHAUS - MILANO - ITALIA" and "BREVETTATO" with a lozenge logo. The piece is complete with its very rare original rigid case from the period, made of embossed burgundy paper, well preserved.
2. Coordinated set of 4 compact bovine bone tools finely turned (Victorian period, late 1800s): a sewing needle/puncture tool, a conical steel awl for punching buttonholes, a tailor’s mechanical pencil/roller, and a hollow cylindrical needle case (agorajo). The handles feature small decorative rings and the typical, fascinating patina of time.
3. Table clamp with pin cushion (Third arm): Victorian wooden turned structure with a functioning screw clamp, surmounted by a green velvet cushion and adorned with an etched metal inlay depicting a stylized fish/dolphin.
4. Antique contemporaneous thimble: In metal silvered/silver with a base band punched with geometric arched motifs and a deep honeycomb pattern.
5. Brass regulating tool marked "OTELLO": The original snap metal clip with arched bridge and toothed bar, used to regulate the depth of the embroidery stitch.
6. Two rare original manuals/advertising leaflets (1920s/1930s):
• Instruction leaflet for the "Wonderful Patented Device for HAND EMBROIDERY" (Representative Del Ponte Otello, Via Plinio 16, Milan), which explains step by step the use of the brass clip and the bone needle to create embossed embroidery and plush/carpet effects.
• Leaflet for the "ITALICO" device for trimmings and braids (Bianco Antonio & C. Company, Via Vitruvio 3, Milan).
Period-used items. The metallic components and bone are well preserved and show the normal patina of time. The wooden clamp has a superficial crack from shrinkage due to age on the curved body (highly visible in the close-up photo), which does not compromise its structural solidity. The paper of the manuals shows natural yellowing, creases, and small marginal tears.
